So I'm currently running an i5 3570k oc'd to 4.2 on a little corsair water cooler with temps consistently running in the mid 30's C. I have been thinking about buying a new board and processor but Im only using a Radeon 270x. Would upgrading to a 4690k be worth the upgrade with a new board or would it just be a waste given my gpu. I have to be honest Im totally happy with my current system I dont need to upgrade. . . but Im sure most of you understand, I NEEEEED to upgrade just because if I dont get new computer toys once every 2 years or so Im not happy. I guess what Im asking here is, is there enough of a difference between the two cpus to warrant purchasing the new board and 4690k.
