Should I upgrade from my i5 3570k @3.4ghz to an i7? Or use the money to buy a second monitor and an 250gb ssd? Bare in mind I only really use it too game and I have gtx 970. But I want the pc to be future proof for another year at least. I've heard the i7 isn't worth it for solely gaming but I want to be sure. The main games I will be playing will be wow, battlefront and fallout 4.
