Yesterday we blogged the latest quad SLI, dual core PC aimed at gamers - which is not yet available in the UK, but we've been assured by Alienware will be soon.

Today, ATI and Mesh have got in on the act. PCs running two ATI graphics cards in Crossfire configuration hasn't been anything like the success of Nvidia's SLI systems.

According to the Steam survey this morning when we looked, just 95 of its registered 702,933 users were using Crossfire-enabled PCs, compared with over 5,000 running twin card SLI machines.

That's in no way the total number of sales, but a good indication of popularity among users, so this is a big test for ATI - and you could argue a gamble by Mesh.

Mesh Matrix² XFR PCs start from £799, but that gives you a single X1300 Pro card, with a 2GHz Athlon64 X2-3800+ (click the links and you can compare their performance to other graphics cards and CPUs we've tested) and a pedestrian 512MB of DDR400 Ram - hardly the blistering performance that will be demanded hardcore gamers, but good enough to satisfy the casual player.

The Matrix² Crossfire range, with PCs running either two X1600Pros, X1800GTOs or the X1900XTs, is more likely to attract gamers.

These cost up to £1,899, and the top end Matrix² Crossfire X1900 has a dual core 2.4GHz Athlon64 X2-4800+ CPU, an X1900 Crossfire with an X1900XT graphics cards and 1GB DDR400 memory - a much more attractive PC for gamers that like to play at higher resolutions. It  also comes with a 20inch Viewsonic VA-2012W TFT, which we tested back in January, and gave 3 out of 5.
