I just sold my 2700x and bought a 3700x it should arrive on Tuesday. I was going to skip this upgrade but decided I would like to play around with some new things this chip can do like per CCX overclocking and infinity fabric ratios.
Looking at reviews the CPU seems to use quite a bit less power at load as much as 75 watts! This should mean this motherboard has even less problems running it than the 2700x. I was going to spend money upgrading the motherboard but think it's better spent upgrading the CPU.
