Looking for the perfect cpu for my gtx 650(value for money)

[Dcm23]

My rig configuration is-
Processor- Intel core i5 3570
Motherboard-Asrock B75 pro-m
Graphic Card-Zotac Gtx 650
Ram-Corsair Xms3 8gb
Smps-Cooler Master Thunder 600w

So,my main problem is that is my processor too much for my Graphic Card and I would be very grateful if you give me suggestions for my configuration,thank to ya'll in advance @dstr86

Don't do any change. Stick with this config. CPU is powerful. I would not recommend changing CPU. Change GPU if you wish to, otherwise no change

I have to agree with EasyLover that cpu is amazingly fast in all games
