Yes, it's fine however the 2700K is needlessly expensive for a gaming system. Just get the 2500K.
What's the difference other then price? Sorry I'm not very knowledgeable haha I've been a console gamer most of my life. Also should I bother with the CPU cooler if I'm not going to be OC'ing my CPU at all. Should I just get another fan for inside the case instead or will the stock fans from the 650d be enough for the 2 gpus.
