Hello, I recently bought a Older Gaming build off the internet for $100. (Intel C2q q8400 2.66ghz, 8gb ddr3 1333mhz ram, radeon hd 4670 512mb (upgraded to 2gb evga 750ti), and a 430w PSU.

My current MOBO is a Intel DP45SG from 2008. I don't really care about a budget price. I just want to know if there is a reasonable upgrade for a CPU while keeping the same MOBO and PSU.

Thank You - Aidan
