I have a desktop pc with an AMD 6500 APU, I am considering upgrading the GPU but I don't want to spend over $100. Is the EVGA 02G-P3-2639-KR GeForce GT 630 2048MB GDDR3 better than the GPU found within an AMD 6500 APU? I don't want to buy a graphic card only to get the same amount of performance. Thank you very much.
