GPU bottleneck?

Hello. I was wondering if an AM3 Athlon II x4 630 will bottleneck with a AMD Diamond 6570PE32G Radeon HD 6570 2GB 128-bit GDDR3. I will be running it at light gaming with a 430W PSU. I need to be cheap, but I don't want a bottleneck. 

Nah, wont bottleneck

Alright, how well will it perform though? I'm currently using a 4200 for my GPU. I barely get 10FPS on 640x480 on Borderlands 2 with lowest settings.
