I've just bought the game today, and from what i can see it should run perfectly fine on my computer. I've tried changing the screen size and turning the hardware acceleration thing off, all to no avail, my stats are
radeon hd4350 graphics card, 3.2ghz single core, 4gb ram, windows xp 2002, ide hard drives with plenty of space, hope this helps, im so hanging out to play the game
