WTB Gaming Computer $500 max

[ha2fb]

I'd like to purchase a gaming computer within 1-2 weeks. I'd prefer to have at least the following:

Quad Core Processor
2GB Ram
512MB Video Card
OS installed * (doesn't have to be, but would be nice)

$500 is my limit as to that is what I've saved. So let me know if you have anything of this sort.

Same here, but I want a dual core at least 3.0
