Right now my motherboard is a low end gigabyte m3970am-hp, and my processor is an AMD fx-6120. My GPU is a XFX radeon 7750, I have 10gb of RAM, and a 550w PSU. I want to overclock my processor, but I have a low end MOBO, so i'm looking to upgrade. I am also looking to get a better processor. What are some recommendations?
