I would recommend it to anyone, I love it!
I have a similar problem, but only when playing in surround. Occasionally at 5760x1080 one of my side monitors will go black for a few seconds then come back on. One of them is hooked up with the DVI and the other is a DVI-DisplayPort adapter. However, my VG248QE has never had any random black-screen issues and I've always had it connected via DisplayPort.
An EK waterblock for the 980 is next on my list!
I have been getting this comment a lot. The only reason I went with the i7 was because it was on sale for $249.99 at my local MicroCenter when paired with a new motherboard. It was worth the extra $10 over an i5 4670k or something similar.
