So far this is what I have (bought):
CPU: Intel E6750 2.66G
CPU Fan: CoolerMaster Hyper TX2 or CM GeminII (but need two fans)
RAM: CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
Case: Antec 900
Mobo: GIGABYTE GA-P35-DS3L LGA 775 Intel P35 ATX
Video Card: ?
Sound Card: ? (Logitech Z-5500 speakers)

Don't want to spend over $500 (not including what I've already bought). I want to be able to play Test Drive Unlimited at max settings. I also plan on using Windows XP and not Vista. Please recommend where the Question Mark is at.
