dont think that was very helpful...
well id say that getting a 6600GT wouldnt be a bad buy, its kinda low end but when direct X 10 compatable video cards come out it would be in your best interest to upgrade your video card then anyways.
you can get a 6600GT for round 100$ on www.newegg.com just make sure that you know if your motherboard is AGP or PCI express before you buy your card
