Thanks for all the help guys.
I ended up getting a Geforce 7900GT with 256MB GDDR3 ram, 24 pixel pipelines and PCI-E 16x from newegg.com. I was going to go SLI and get two slower, cheaper cards, but my mobo doesn't support SLI I got a regular one instead of a overclocked one, because a lot of people who got the overclocked one had them die on them.
