Palicomp's Excalibur Ballistix E85-4670-19 uses Intel's tried-and-trusted Core 2 Duo E8500 to equal our Best Buy machine's 128-point WorldBench 6 performance. It delivers enough power to breeze through day-to-day computing tasks without a hitch.

Gaming performance is less exemplary, however, and a 512MB HD 4670 graphics card is no competition for the Mesh's 1GB HD 4870. While it's quite capable of playing 3D games, the Palicomp Excalibur Ballistix E85-4670-19 can deliver only half the gaming performance of the Mesh when pushed with the latest titles.

The Palicomp Excalibur Ballistix E85-4670-19's 500GB hard drive and 4GB of DDR2 RAM are in line with the other systems in the chart. Its 19in budget display, meanwhile, offers a decent resolution and the useful inclusion of a digital connector.

The Excalibur is housed in a very tidy-looking case with a full-height front door panel. Finished in silver, this conceals the DVD drive and external drive bays. USB ports are conveniently located at the Palicomp Excalibur Ballistix E85-4670-19's side.

Inside, the Palicomp Excalibur Ballistix E85-4670-19's compact motherboard leaves little room for expansion. Both memory slots are filled and one of the rear chassis slots is taken up by a USB riser.

The Palicomp Excalibur Ballistix E85-4670-19's one-year return-to-base warranty is reasonable but bettered elsewhere.

Buying advice: Budget desktop PCs

Processor: Intel's Core 2 Duo E8500 is a popular choice at this price, although slower processors such as the E8400 will still be fast enough for most users. Low-cost alternatives, such as Intel's E7000- and E4000-series chips, offer weaker performance at any clock speed. AMD's latest offerings, such as the Phenom II X2 550BE, offer excellent performance and good value for money.

Memory: In the age of Windows Vista, 2GB of RAM is essential. The majority of sub-£500 PCs are now fitted with 4GB.

Make sure you're getting the full benefit of the memory - some onboard graphics controllers use system memory, which will slow things down. Check your motherboard has free memory slots if you plan to upgrade later.

Storage: Expect 500GB at this price, but you can never have too much storage space. Digital media content will quickly fill a reasonably sized hard drive. Hard-drive space is easy to add later, however.

If you're planning to upgrade hard drives internally, ensure that you've got spare drive bays inside your PC's case.

Look for a DVD drive that can write to the -R/+R formats at 16-speed or better. If you want to copy 8.5GB to one disc, get a drive that can write to DVD-R DL and +R DL at 12- and eight-speed respectively. Keep an eye out for 22-speed models.

Flat-panel: It's the component you'll be spending all your time looking at, but PC makers often compromise on the monitor.

All the PCs in our chart come with flat-panels. The most common size is 19in - the quality of larger monitors is unlikely to be good at this price. Look for a monitor with a DVI or HDMI digital connector to ensure the best picture quality. Make sure the PC has one, too.

If display size or quality is of critical importance to you, you may be able to get a 22in 1,080p flat-panel if you're willing to cut costs elsewhere.

Graphics card: With the best graphics cards retailing for more than £300, a sub-£500 PC is unlikely to satisfy a hardcore gamer. You'll want a PC that can produce at least 50fps for gaming.

ATI does well in this price bracket and, thanks to recent price reductions, we're seeing HD 4670 cards appearing once again. The HD 4770 and HD 4870 provide very good budget gaming performance.

For nVidia and ATI cards, always look for a 1GB rather than 512MB version if possible. If you don't play games at all, consider purchasing a machine that relies on the integrated graphics of its motherboard - you'll save a packet.

Power supply: Expect only a basic PSU at this price point. Without power-hungry components installed, there's simply no need for a more powerful supply. If you plan to upgrade your system - and in particular the graphics card - then your PSU must be able to deliver enough juice to power your new components. A 450W or 500W model is a good starting point.

Sound card and speakers: You're unlikely to get a standalone sound card at this price point. Most motherboards have built-in chips that can handle six-channel sound. To get the best out of them, you'll need a 5.1-channel system (five speakers and a subwoofer). Separate stereo speakers are rare in systems costing less than £500, however.
