The only reason I asked what kind of processor is this: if it's a Pentium, ATI cards tend to work best because the Pentium's architecture can handle the demands of the graphics card. If you're using an AMD or a Celeron, it's best to go with a graphics card with an nVidia chipset, because they are, in effect, mini-motherboards designed to handle all of the graphics processing demands with liitle to no CPU system resource hogging.
