I have a Dell Precision 490 with a Foxxconn ls-36 mobo, 4 gb RAM, a Radeon HD 7770, and two Intel Xeon 5160 Dual Core CPUs running at 3 ghz. I recently bought the 7770 GPU and installed it. Everything went fine, but the CPUs are holding me back now as far as gaming goes. I guess the GPU is being bottle necked by my CPUs. So my question is: what are the best dual CPUs that I can buy that fit in my motherboard? I would like to play games like GTA 4, Battlefield, and Call of Duty, because my processors now are preventing me from playing them. Thanks for the help.
And get something like a 7950 or R9 270x for 200$ only!
