Need help finding both a graphics card and processor!

Hey all, I just wanted to get some opinions on the best processors and graphics cards to run Mass Effect 2 on a 1680 x 1050 resolution. However I am on a budget of $150-$200 for the cost of the graphics card and processor combined. Also, I've already looked at the benchmark charts for Mass Effect 2, I'm just asking you guys to give me your opinion on the best "bang for your buck" graphics cards and processors.

The combined price for both the graphics card and processor must be under $200!

Thanks in advance!
