I have a little over $300 to upgrade my pc. I want to buy components for maximum performance.
My current build is:
M68MT - Mobo
Amd FX 4100 - CPU
8gb DDR3 2x4gb - Ram
Evga Gtx 660 - Gfx
500gb Hdd - Storage

I was thinking its my mobo/cpu but could it possibly be my hdd or ram?

All insight is appreciated Thank you

On my phone sorry for typos
