Q: pci e and will support many things including direct x 10 and will run most games i saw the nvidia gforce 6800 is that any good? something 100 bucks or less?
A: a really high end card will cost you over $400.00 the 6800 is old and crappy the best thing you can get for $100 if you shop around is an 8800gt. (These are a good gaming card though) You will need a pci-e slot and a 400watt or higher power supply
