GeForce cards work good....unless you get the new ones...and you need lots of RAM. I\'d also recommend an AMD Athlon, since they\'re so much faster than Pentiums, but that would cost a bit...
My AMD Athlon has a pipeline speed of 333mhz, whereas my brother\'s P3 only has 100mhz pipeline, making his games go about 3X slower...
Newest Athlon has 1.6ghz pipeline, while newest pentium has 800mhz pipeline. Pentium better for processing, Athlon better for gaming.
Be sure to get atleast a 64mb video card, or newer games will not run.
