Desktop buying guide

Processing power

A PC's processor defines how well it handles the most basic of tasks. The faster your processor, the snappier the operating system will feel and the faster you'll be able to perform complex tasks such as photo and video editing. The more cores a processor has, the better it will be at performing multiple tasks at the same time without feeling the strain. It'll also dramatically improve performance in programs that support multiple cores.

You'll be hard pressed to find a modern PC with less than two cores, and most of the PCs nowadays have four. Processor speed is also very important, and a few system builders have taken the opportunity to boost performance by overclocking them.

This is something you can do at home, but it requires a lot of patience, experience and there's a fair degree of risk that you could permanently damage your PC by doing so. Professional PC builders typically stress test their PCs to ensure their overclocks won't shorten the life of your system.

Graphics cards

If you're looking for a gaming machine, though, processor speed is not the most important factor that will define its in-game performance. It's your graphics card that will handle the visuals for your games. You'll ideally want to have discrete graphics cards, forgoing the onboard graphics capabilities of their CPUs. 

You can get some very capable graphics cards in a system costing less than £700, all of which can be expected to play all of today's modern games at Full HD resolution. Whether you're able to crank up the eye candy to the max depends on what card your system has. The upper mid-tier cards such as the Nvidia GeForce 760 and AMD Radeon R7 265 and upwards have the power to run the latest games at their highest settings, while those beneath them may sacrifice some fidelity to maintain a consistent frame rate of more than 30fps in the toughest games such as Crysis 3. If you're not cost-constrained, spending more on a system with a more powerful graphics card such as the AMD Radeon R9 290 or Nvidia GeForce GTX 970 can see you playing the latest titles at 4K resolutions.

Storage space

Whatever you're using your PC for, you'll want somewhere to store all your data. The ideal scenario will see you having your operating system installed on an SSD, which provide super-quick read and write speeds making your computer feel more responsive. SSDs can be pricy when it comes to capacity, however, so it's best to pair these with a secondary hard disk where you can store your media and documents.

PC Case and PSU

If your PC is a long term investment that you want to upgrade in the future, you should carefully inspect both the case and the motherboard. Some smaller cases don't leave much room for big graphics cards and don't have many extra bays for hard disks or optical drives. Furthermore, the motherboard might not have enough spare ports for extra components. Look out for PCI-E slots if you want to install an extra graphics card or wireless adaptor, and check how many SATA ports are free if you're planning on investing in extra storage. If you're installing high performance storage such as an SSD, you'll need to make sure there are spare SATA3 ports, as slower SATA2 ports won't be able to take advantage of the higher speeds offered by solid-state storage.

Look out for extra RAM slots, too. Some motherboards will have four spaces for memory modules, but the PC builder might have only filled two. This means you could buy more RAM later when demand requires it. You'll also want to make sure the power supply unit (PSU) can provide ample power for any future upgrades.


If you're starting from scratch with a brand-new PC,  you shouldn't settle for a poor monitor. There are many quality screens available at extremely competitive prices. All the monitors in this test measure at least 23 inches diagonally, with some stretching to 24 inches. We look at colour coverage, accuracy and contrast levels, and you should also pay attention to the what screen technology a monitor is using. IPS panels offer the richest and most vibrant experience, but they are more expensive. TN panels, meanwhile, vary wildly in quality and are typically cheaper than IPS screens. They have fast response times but the cheapest of them have narrow viewing angles and disappointing colour coverage. We'll let you know in our reviews if the supplied monitor isn't worthy of your cash. 

Windows 10

Until the end of July 2016, any PC running a legitimate copy of Windows 7, 8 or 8.1 is eligable for a free upgrade to Windows 10, Microsoft's latest operating system. Most of the systems listed here will ship with Windows 10 pre-installed (we reviewed them with Windows 8.1 installed), but depending on the age of stock, you may sometimes find yourself with a Windows 8.1 PC instead. The upgrade process to Windows 10 isn't particularly long or difficult, but the 3GB software download required may be achingly slow depending on your internet connection. We'd recommend upgrading to Windows 10 as soon as you start using your new PC, so you can immediately get used to the updated user interface and more desktop-friendly design as soon as possible.

Some of the custom PC builders listed here will also supply your PC with Windows 7 or 8.1 if you'd prefer; this is something you have to choose during the customisation process.

We have a number of guides on the process, including how to install Windows 10, and a series of articles on Windows 10's new features

Best Desktops 2015

Best desktops for under £1,000

1. Acer Revo One RL85

The Acer Revo One has one of the cleverest small form-factor PCs we've ever seen. Its tiny chassis has room for three hard disks meaning you can use it as a dedicated media PC for your living room or even set it up as a Windows-powered fileshare if you want. It's not the fastest PC on the planet, but its dual core Intel Core i3 processor and onboard graphics are capable of playing Full HD videos just fine, which is about as much as you can expect. Depending on which model you buy, you'll also get a handy remote, perfect for those looking to avoid the inflexibility of a keyboard and mouse pairing

Processor: Dual-core 1.7GHz Intel Core i3-4005U, RAM: 4GB, Front USB ports : 0, Rear USB ports: 2x USB, 2x USB3, Total storage: 2TB hard disk, Graphics card: Integrated Intel HD 4000 graphics, Display: N/A, Operating system: Windows 8.1

2. Zotac Zbox Nano Ci321 (Plus)

Zotac Zbox Nano CI321 Plus

Media streaming PCs are at their best when they're small, subtly styled and quiet, and the Zotac ticks all those boxes. In fact, it's completely silent, with passive cooling possible due to the incredibly low TDP of the Celeron processor inside. Of course, such low power results in fairly leisurely performance, but as long as your needs are modest, you'll have no issues. 

The other benefit of this PC is that it's easily upgradable. There's a proper 2.5in SSD inside which can easily be removed, and you can also upgrade the RAM, too. For just £230 it's a bit of a steal and worth the money for anyone who wants to add to their home cinema setup on the cheap.

Price when reviewed: £230. Read our full Zotac Zbox Nano Ci321 (Plus) review for details.

3. Asus Chromebox

Asus Chromebox front angle

The Asus Chromebox isn't for power users or even those who want a media streaming PC. It is however perfect for somebody with very modest needs or even a child who only needs a fairly limited, web-based PC for their bedroom. It may not have heartrate-boosting specifications, but with the lightweight Chrome OS installed performance still feels genuinely sprightly. 

Working on documents, browsing image-heavy webpages and watching online videos is quick and easy, and you'll have no problem doing all the basic tasks you'd normally do on a much larger PC. A keyboard and mouse are supplied, but you'll need a monitor in order to use the Chromebox. For £208, it's a great buy.

Price when reveiwed: £208. Read our full Asus Chromebox M031U review for more details.

4. Palicomp AMD Kaveri Evolution

Palicomp AMD Kaveri Evolution

It's always a joy to see manufacturers push the boundaries of what you can expect in a budget PC and this is what Palicomp have achieved with the AMD Kaveri Evolution. We've been massively impressed by the capabilities of the AMD's Kaveri processors, and this budget PC shows them off to great effect. It has a powerful processor that's been capably overclocked and offers reasonable upgrade potential. You also get a big, good-quality 24in monitor that lets you enjoy movies and games comfortably. It also uses a 1TB SSHD that uses 8GB of NAND cache to help Windows feel responsive and bootup and shutdown super swiftly. This system offers a wonderful combination of application and gaming performance that makes it a good all-round home PC. This is quite simply one of the best PCs you can get for £500.

5. Palicomp Intel Haswell i5 Commander

Palicomp Intel Haswell i5 Commander

Palicomp has assembled a great selection of components, and we particularly like the AMD Radeon R9 270X graphics card. It's ideal if you want to buy something that can play the latest games at the highest, or very nearly the highest, quality without spending a lot of money. You also get a 60GB SSD as well as a 1TB hard disk for storage, and the SSD in particular made Windows 8 feel super responsive although its actual storage capacity is low. The Palicomp Intel Haswell i5 Commander is a great combination of both value and performance.

Price when reviewed: £650. Read our full Palicomp Intel Haswell i5 Commander review for details.
Processor: Quad-core 4GHz Intel Core i5-4670K, RAM: 8GB, Front USB ports : 3, Rear USB ports: 6, Total storage: 60GB SSD, 1TB hard disk, Graphics card: 2GB AMD Radeon R9 270X, Display: N/A, Operating system: Windows 8.1

6. Chillblast Fusion Obelisk

With the Chillblast Fusion Obelisk you get a system equipped with a quad-core Intel Core i5-4690K and an AMD Radeon R7 265 that means it packs a both good application performance and gaming potential. The CPU is overclocked to 4.2GHz and temperatures are kept under control with an Akasa CPU fan. Impressively, the system manages to still run whisper-quiet even when put through its paces. Paired with a Full HD 23in Asus VS239HV IPS monitor you get a quality complete PC package. The Chillblast Fusion Obelisk is great value at £700.

Best desktops for over £1,000

1. Yoyotech BlackBox DB3

The Yoyotech Blackbox DB3 has a gigantic transparent side panel that gives you a glimpse at its powerful components. An Nvidia GeForce GTX 970 gives the system plenty of gaming punch and the eminently powerful six-core Intel i7-5930K is well-cooled by a Corsair liquid cooler.

You also get plenty of storage space and we were pleased to find the Yoyotech BlackBox DB3 ran quietly, even when its adjustable fans were set to performance mode, meaning the noise never became distracting. It has an MSI X99S Gaming 7 motherboard that will also mean future upgrades are well accommodated.

Price when reviewed: £1,735. Read our full Yoyotech BlackBox DB3 review for details.

2. Chillblast Fusion Ares

The Chillblast Fusion Ares is a breathtakingly beautiful and well put together PC that uses a powerful six-core Intel Core i7 “Haswell-E” processor and a high-quality Intell X99-based board all housed within an elegant and understated NZXT H440 case. A quality Samsung 840 Evo SSD makes everything feel super responsive and the2GB VTX3D Radeon R8 285 X-Edition GPU brings great gaming performance, making the Fusion Ares a fantastic all-round performer.

3. Apple 27-inch iMac 2014

You know what to expect from an Apple iMac: a powerful all-in-one computer with a fantastic display and looks to shame a supermodel, but a slightly wince-inducing price. This late 2014 version of the 27in iMac is all of those things and now with a stunning 5K display with a resolution of 5,120x2,880.The display itself is also phenomenal and especially useful if you need a lot of room to work with. It also has fantastic colour accuracy and contrast. If you can afford the iMac, it's impossible not to fall for. The ultimate all-in-one.

Price when reviewed: £1,999. Read our full Apple 27-inch iMac review for details.
Processor: Quad-core 3.5GHz Intel Core i5-4690, RAM: 8GB, Front USB ports : 4x USB3, Rear USB ports: 0, Total storage: 1TB Hard disk, Graphics card: AMD Radeon R9 M290x, Display: 27in IPS LCD, Operating system: OS X 10.10 Yosemite

4. Scan 3XS Z97 Performance GTX

Scan 3XS Z87 Performance GTX

The Scan 3XS Z97 Performance GTX strikes a good balance between scintillating application performance and gaming punch thanks to its combination of Intel's Core i5-4690K 'Devil's Canyon' CPU and Nvidia GeForce GTX 770 graphics card. Since our review, the graphics card has been upgraded to a GTX 970 but the price has remained around the same, so this is now better value than ever. The system is also incredibly well assembled and includes a dedicated sound card to boot. There's also decent scope for upgrades and the system is equipped with 8GB of fast memory. This all makes the 3XS Z97 Performance GTX a great mid-range gaming PC and excellent value.

Price when reviewed: £1,200. Read our full Scan 3XS Z97 Performance GTX review for details.
Processor: Quad-core 4.7GHz Intel Core i5-4690K, RAM: 8GB, Front USB ports : 4, Rear USB ports: 6, Total storage: 256GB SSD, 2TB Hard disk Graphics card: 2GB Nvidia GeForce GTX 770, Display: N/A, Operating system: Windows 8.1
