Well, that won't run gta, i'm telling you now. I have an ATI Radeon HD 5450 and it is not the best, but it is cheap, and with a performance mod, you can run GTA with it with no lag. I can run most games on medium or high, not ultra, but medium is pretty good, just a little decrease in look, but with very good performance. I reccomend one of these if your computer can handle it, maybe a little better card if you can afford, but the lower end of the ATI 5000 series is cheap but great.
