if you use it most for gaming you should buy the the SAPPHIRE HD7850 1GB with ATHLON II X4 651K. cpu is good enough for some rendering, but don't expect it will be fast or slow. but for gaming the cpu is good enough
Look at the pentium G series CPUs they perform very well for the price. If you give us your budget for CPU Board and GPU we can make better recommendations. Also you are aware the CPU you mention run on different motherboards?
I don't have a big choice between CPUs because I'm buying all the parts from the same website and I live in a small country so.. I just wanted to ask you about those 2 choices.. and Yes, I am not the biggest tech specialist but I know the basics..
If you have any recommendations I would like to hear them..
About the 660ti : I don't need that much power since I am on a 1360x768 monitor. And I can overclock the hd7850 to 1000 - 1050 Mhz in time if needed because I have around 250W spare since I am buying a well priced Case with 600W PSU .
