I have the 6800gs AGP on my system, its pretty nice and manages to play everything fairly nice on high settings at 1024x768 or 1280x1024. Don't count on unlocking it though, some won't unlock because of damaged pipes (mine won't), you can easily get a decent overclock on it though (I tested mine at 400mhz, but chickened out to 380 since I need this card for at least 2 years). Overall it's a great card for the cash, probably be able to play all new games on medium/high settings for a while... until direct x 10 at least.
