Im running a GTX 1070 and an i3 3220, i was doing some tests and the majority of the time my processor is at 90%+ usage. and my gpu at around 40 - 60. i would guess this means an upgrade is needed. I was looking around and i5 3570 seems to be a good option for LGA1155 socket motherboard. Has anyone got this processor or got any recommendations on another good upgrade?
