Bit-Tech take a look at the Rock Xtreme SLI notebook which comes standard with an AMD Turion 64 ML-42 processor (2.4GHz, 512k L2 cache), 1GB of DDR400 RAM, 19" 'glossy' widescreen at 1680x1050, Two GeForce Go 7800 GTX cards in SLI, 100GB 7200RPM hard drive and 8x DVD writer.

The graphics power really is so far beyond anything we've ever seen in a notebook. The NVIDIA GeForce Go 7800 GTX was really desktop-level performance, and this takes it to SLI-desktop-level performance. The limitations of notebook processors and motherboards are such that you're never going to get 100% of desktop performance in a 'portable' system, but with this you really are getting about as close as humanly possible.

The major stumbling block to the particular system that we have here is the fact that the screen is so low resolution. If you have SLI, the minimum you want to be running is 1600x1200, in my opinion, and this screen tops out before you get to that. 1920x1200 would be a really nice size to be running at, and would allow you to stretch your graphics subsystem to the limit.

At just over £2300, it's not a cheap bit of kit. In fact, you could build a very, very cool desktop system for that amount of money, so you really will have to want the base level of portability that the Rock notebook offers to justify buying it over a standard system.
