Dell Latitude D820

Not as good as the Precision, but still a tool for gaming, the Dell Latitude D820 can also be used for 3D modeling and video-editing. It's got the same 4GB memory capacity, a Intel Core Duo Processor T7600, a 512MB Nvidia Quadro NVS 120M TurboCache 2 video card (damn that's a long name), and a 1920x1200 LCD display. Total HDD capacity up to 100GB.

So again, if the Precision is too steep for your budget, then take the Latitude if you can afford it. Well worth it and still a very nice machine to play your games on.
