I just recently got the GTX 1070 G1 Gaming edition and I was wondering if I should upgrade my cpu to the i7 4790k. I have the i5 4670k (never been overclocked) which i've been told shouldn't bottleneck the GTX 1070. The reason i'm asking this is because I have a Thermaltake Water 3.0 Performer C collecting dust on my cabinet and i'm wondering if I should go through the hassle now and install it or should I get the i7 4790k and install it then? Does the i7 4790k offer benefits worth upgrading to it or just stay with my current cpu and install the water cooler?
