That's a terrible idea for more than one reason. It's not going to be that cheap since it hasn't been made for a while. Axolotl2 most likely doesn't know much about computers if he recommended a card that came out 4 years ago, and is pretty much a just a 8800 which came out 5 years ago.
Nobody could give you a good answer to this question though. First whats your budget, and second what are your specs. You should have the op have a bit more information or post in the computer megathread with some actual information.
EDIT: I didn't even noticed you bumped this. Why haven't you bought a gpu yet, it's been about a month.
