Very fast and extremely expensive, the Chillblast Fusion Titanium is an adventurous and highly impressive PC that achieves some of the best performance benchmarks we've ever seen.

In the Power PC price category it's performance that counts, and the Fusion Titanium has buckets of it.

Intel's Core i7 processor family has swept the board here. Although all the PCs in our chart use the entry-level 920 model, we're seeing some excellent test results. In WorldBench 6, the Chillblast Fusion Titanium's score of 135 is exceptionally good - particularly so for quad-core CPUs that don't tend to shine in our benchmarks.

The Chillblast Fusion Titanium's Asus P6T motherboard is fitted with 6GB of DDR3 memory, which is perfect for a PC so well equipped for multitasking.

A huge one-terabyte (1TB) hard drive is also provided, but it's the Chillblast Fusion Titanium's 30GB OCZ core V2 solid-state drive (SSD) that's caught our attention. By using memory chips rather than rotating disks, these drives can significantly boost the performance of certain disk operations - particularly boot times.

Unfortunately, SSDs are still rather expensive, and only relatively low-capacity models are affordable. The 30GB example provided in the Chillblast Fusion Titanium isn't really suitable for a Vista installation, and prospective purchasers will need to make sure their applications are installed on the disk drive if they want to avoid rapidly running out of storage space.

An ATI Radeon HD 4870 X2 card delivered the best graphics test results of the group, with the Chillblast Fusion Titanium's Crysis framerates particularly impressing when quality levels and screen resolution were increased.

A 24in display and a set of five surround speakers and subwoofer complete the package, enabling full-HD playback from the Chillblast Fusion Titanium's Blu-ray-capable DVD writer.

Power desktop PCs buying advice (April 09 issue)

Processor: Until recently, Intel Core 2 Duo chips were your best bet. This has all changed with the release of Intel's incredibly quick Core i7 CPUs. These offer a number of speed boosts, including the ability to run eight threads simultaneously, although they require far more expensive motherboards and memory than previous-generation chips.

Memory: If you're spending more than £1,000 on a PC, it should come with at least 4GB of RAM. Any less will prevent a Vista PC reaching its full potential. To plan for the future, get 4GB in two modules to allow room for expansion.

A 64bit operating system will ensure you take full advantage of your memory, especially if you're using dual graphics cards - these sap RAM on 32bit systems. If you're going for an i7-based PC, you'll need to buy your chips in threes to take advantage of the triple-channel architecture. You'll also need to splash out on DDR3 rather than DDR2 chips.

Storage: Expect at least 750GB. Look for a pair of drives rather than a single larger unit; it will boost performance and prevent you losing lots of data if a drive fails. Raid setups are also an option. Consider mirroring for added security.

Cover backup with a multiformat DVD writer. Dual-layer capabilities (allowing you to store 8.5GB rather than 4.7GB on a disc) are useful. Make sure the drive supports DVD+R DL at eight-speed or above - some more recent drives offer twice this speed. You should also be able to get eight-speed DVD+RW.

If you want Blu-ray playback, be prepared to compromise on DVD speeds. Alternatively, buy a second DVD burner for backup.

Display: We're seeing increasing numbers of 24in displays. This used to be the magic size at which full 1,080p HD playback became available, making these ideal partners for Blu-ray drives. However, newer 22in monitors in the 16:9 aspect ratio are also able to display full HD video and cost considerably less, making them excellent value for money, although the size of onscreen elements will be reduced.

If this doesn't appeal, standard 22in displays are excellent value. Make sure you get a digital input for the best image quality and additional inputs if you want to attach other devices. An HDMI is useful for connecting to a games console.

Graphics card: For a thrilling gaming experience, choose between an nVidia GeForce GTX 280 and ATI Radeon HD 4870 X2. Also look out for pre-overclocked graphics cards, which can deliver excellent value for money and are approved by chip manufacturers.

Buying a single-card solution keeps your options open for adding a second card later. It also leaves more space in your PC for sound cards or TV tuners.

Sound card and speakers: There have been improvements in onboard sound, but it's still no match for a decent sound card. You should be able to get a Creative Audigy or one of the excellent X-Fi cards.

If you only want 2.1-channel sound (two speakers and a subwoofer), make sure they're high-quality models. Some firms are bundling 5.1-channel speakers.
