Please disregard the fact that I have watercooling on a locked CPU. I really just wanted to try out water cooling and my friend was getting rid of his h100i GTX. It's really mix and matched too, since this was built over the span of like 6 months so whatever I could afford at the time is what I bought (I modded the case to fit the radiator too) and the CX series psu wasn't my first choice but it was the best I could get at the time. I was running a HD 7950 but that died about a week ago so I'm currently running no GPU and it's kinda killing me a little on the inside.

I mainly use this for gaming and should have about $600 to spend on black friday/cyber monday for parts. What do you guys think that I should get for an upgrade on performance, mainly a GPU though. I was thinking maybe a mobo upgrade too since the d3h lacks in terms of features hardcore. Maybe a 970 and a h97/z97 board? or hell maybe even go all in and get a z170 board a 970 and a skylake cpu.
