Which graphics card?

It will be hard to recomend to you a video card judging by your build list your budget is extremely low and you need to make up for the fact that your going with AMD for a cpu. It would have been easier to get your target fps with an Intel cpu , but that would not have been good for your low budget.

This might work for you and the price might be low enough but you'll have to be the judge of that since you didn't say what the budget was for the video card. $89.99 after rebate.
