I have a gaming pc that has a 1060 6gb vram, 8gb ram, i-5 6600 and i am looking to upgrade it. I am already set on getting more and faster ram and I'm unsure what to upgrade in terms of my CPU. I was looking to upgrade my i-5 6600 (unoverclockable) to one of the coffee lake proccessers, the i-7 8700k in particular, however I don't know wether or not my gpu will be a bottleneck or wether or not the upgrade will even provide a significant difference in gaming performance. If you guys could please help me decide it would be much appreciated. I would also like to know wether or not air cooling will be sufficient in cooling a CPU with the performance of the i-7 8700k.
