Go for the Phenom II, it will be fully compatible with your board, and provide full worth for your GPU.

Only other thing i can find is this, which is a quad core phenom, it should stop the bottleneck.

That is the only place that sells that chip too^

 

Phenom II's are still very good CPU's, yours is a dual core which is the bottleneck.

Or get a new mobo and get something like z87 mobo with 4670K. Though it will probably require new RAM as well and cost you a lot more. horgen123

[QUOTE="AMD655"] Go for the Piledriver 4300 if you can, it is a better processor than the Bulldozer 4100.AMD655

[QUOTE="ricky8741112121"]

[QUOTE="AMD655"] I would suggest grabbing a FX 6300, but do not get anything higher as your motherboards VRM's are on the weaker side, it should handle a stock clocked 6300 without too many problems however.AMD655
