Like the top two PCs, CyberPower’s Gamer Infinity XT Elite is based on the E8600 chip. It’s another strong budget PC performer, albeit some way behind the Chillblast Fusion Osiris and Arbico Elite 8850 Pro.

Gaming performance, however, is a little higher, thanks to the CyberPower Gamer Infinity XT Elite's nVidia 9800 GTX+ graphics card. This shows a small performance gain over the ATI Radeon HD 4850 in many games, including Crysis.

The white, smart-looking 22in Fujitsu-Siemens display is a pleasing inclusion, featuring a two-port USB hub and an adjustable desk light and pen tray. It also offers VGA, DVI and HDMI inputs, composite video and S-video for legacy kit and built-in stereo sound – which you’ll need because the CyberPower Gamer Infinity XT Elite comes without external speakers.

The CyberPower Gamer Infinity XT Elite's case seems targeted at gamers, with its transparent side panel, interior lighting and ‘bubbling liquid’ tube lights. A small door conceals a pair of front-facing USB ports and audio connectors, although this is situated at the very bottom of the case – inconvenient if your PC sits on the floor.

Inside, there are plenty of spare motherboard slots for expansion cards and memory upgrades and the case is well ventilated. There’s also ample room inside the CyberPower Gamer Infinity XT Elite for additional hard drives and optical drives.

Buying advice: Budget desktop PCs (Feb 09 issue)

Processor: Intel's Core 2 Duo range offers almost unbeatable performance for the price. The 3.33GHz E8600 now supersedes the E8500 as the CPU of choice, appearing in the vast majority of desktop PCs in this price category.

Alternatively, go for one of Intel's latest quad-core chips, such as the Q9300. These processors are performing well with newer applications and games. Older Q6600 chips offer good performance with multithreaded apps, but only go for them if the price is right.

Memory: If fast processors speed up your PC, a large bank of memory stops it from slowing down. Get the most out of your CPU by including at least 4GB of RAM. You can get by with 2GB, but your PC will run more smoothly with 4GB.

Storage: Digital media will quickly fill a reasonably sized hard drive, so buy the biggest you can afford. A 400GB-500GB drive will make a good investment. If you've got space, consider a pair of smaller drives - a terabyte (1TB) is a huge amount of information to lose in one go.

Your DVD drive should write to the -R/+R formats at 18-speed or better. Eight-speed rewriting is good; if you want to copy up to 8.5GB at once, look for fast DVD-/+R dual-layer drives. Drives that can read Blu-ray are becoming affordable, but they're still quite rare at this price.

Display: Many PC manufacturers make sacrifices here to keep the price down. But a poor monitor can ruin your computing experience - try it out.

At this price you may get a 19in, 20in or 22in model. Be aware that 19in displays offer lower resolution; 20in and 22in displays offer the same resolution, with 22in models displaying larger icons.

A DVI or HDMI connector will provide a considerably better image than a VGA port, so look for a display with a digital input; if you want to connect additional devices you'll need at least two. Finally, look for a good response rate: 8ms or below should be fast enough for games.

Graphics cards: Hardcore gamers are unlikely to be happy with a sub-£750 PC - after all, the top graphics cards alone can cost £400. But you should be able to find a decent card at this price.

We test PCs on the three-year-old game Fear, and Crysis, a far more demanding title. Although 50fps is enough to make a game playable, you can set your sights higher in this category - look for 80-100fps for decent gameplay. Just don't expect to run cutting-edge titles at the most demanding settings.

ATI's Radeon HD 4850 and Radeon HD 4870 and nVidia's GeForce 9800 GTX+ graphics cards deliver excellent performance and value for money, making even cutting-edge games playable if you drop the resolution and settings a notch.

Sound card and speakers: You may find a budget sound card at this price point, but most motherboards depend on a decent built-in audio chip that can handle six-channel sound. To get surround sound you'll need a 5.1-channel system (five speakers and a subwoofer). You may be offered a 2.1-channel stereo system, which will be good enough for most users. A monitor's built-in speakers seldom offer a satisfying audio experience.
