With its generous software bundle, great mouse - ooh, and a free T-shirt - this is a superb system. Shame you'll have to remortgage the house to buy it, then spend even more on some essential features.

Quite simply the most powerful, expensive, cool, blow-your-socks-off gaming computer we've seen to date, incorporating the stunning SLI graphics system, great sound and acres of storage in a beautiful package. All of which comes at a high price.

A gamers dream, Looks fantastic

Missing some key features, Extremely expensive, Short warranty

With its generous software bundle and great mouse, this is a superb system. Shame you'll have to remortgage the house to buy it, then spend even more on some essential features.

Fast PC ; Easy to upgrade

Open PCI Express X1 slots are blocked

Very fast, expensive PC with two graphics cards will appeal to hard-core gamers and graphics pros with deep pockets.

Distinctive case. Liquid cooling for overclocking and noise reduction. Overclocked graphics cards. Sound-deadening matting. 500GB of hard drive space. Astronomic performance

Graphics not liquid cooled. Pricey

If you have a preference for the Alienware brand, the Aurora will fulfill your gaming needs with aplomb. For the $5,600+ price that Alienware is charging for the Aurora, however, there are better choices in the gaming ranks.

Good gaming performance. Not as expensive as 7900 Quad SLI systems. Tested configuration comes with Logitech gaming keyboard and mouse

Pricey for a system without monitor and speakers. Cooling fans are obnoxiously loud

The Aurora 7500 uses some excellent technology, but there are better choices out there.
