Buying advice: Budget desktop PCs (June 08 issue)

Processor: The once all-conquering E6850 processor has almost disappeared from the chart, outrun by the mighty E8500 chip – you can put in half the RAM and an E8500 will register the same performance scores. The E8500 will be a little more expensive, however, so it’s worth watching out for special offers as manufacturers try to offload their supplies of E6850s.

If you’ve got one eye on the future, consider a Core 2 Quad chip. You’ll sacrifice a little speed for the money now, but you might make it up in spades when multithreaded software applications start hitting the shops.

Memory: It’s a sign of how important memory has become that, even in the sub-£750 category, 2GB is the bare minimum, with most systems stretching to 4GB. If you’re on a budget, there’s no need to go quite this far, but 2GB is a definite must. Memory is only going to become more and more important in the next 12 months, so stock up now.

Storage: You can never have too much storage space. Digital media files such as video and music will quickly fill a reasonably sized hard drive, so buy the biggest you can. A 320GB or 400GB drive should make a good investment.

It’s a good idea to keep large files archived on DVD, so make sure your PC has a DVD burner. Look for a drive that can write to the –R/+R formats at rates of at least 18-speed. Eight-speed rewriting is good; if you want to copy up to 8.5GB at once, look for a drive with DVD-R DL or +R DL. Write speeds on these have got significantly faster in recent months, and you really need to be looking for an absolute minimum of eight-speed.

Display: Compromises have to be made to keep down the price of a PC and the monitor is often where the sacrifices start. Just remember that this is the part of the PC that you’re going to be spending most of your time looking at.

Virtually all PCs come with flat-panels. We’d recommend a 19in or 20in model – they’re common at this price point. Be very careful, though, when offered anything larger than 20in, as the quality at this price point could be low. Finally, look for a screen with a good response rate – 8ms or below should be more than fast enough.

Graphics cards: Given that the best graphics cards can retail for £300 or £400, feverish gamers are unlikely to be best served by a sub-£750 PC. Nonetheless, the best PCs do tend to come with decent graphics cards.

Although 50 frames per second (fps) is enough to make a game playable, at this price you can set your sights a little higher. Choose one that can manage 80-100fps on a number of titles. The 512MB 8800 GTS 512 is your best option if you find one, although the 8800 GT isn’t far behind. You may be able to find an 8800 GTX if you hunt hard enough, but the GT and GTS 512 are more likely. Stocks may be running a little low.

Sound card and speakers: You’re unlikely to get a standalone sound card at this price point, as it’s an area where vendors are likely to cut costs. Most motherboards have decent built-in audio chips that can handle six-channel sound, but to get the best out of them you’ll need a 5.1 speaker system. Unfortunately, you may not get anything better than a 2.1 system in this category – indeed, you won’t necessarily get a subwoofer at all.

OUR VERDICT

Despite its less than inspiring WorldBench score at stock speeds, the Chillblast Fusion Cobra is an attractive option for gamers and fans of overclocking.
