@helloWorld, 2600k @ 4.8, water cooled I assume? should defiantly upgrade your cpu wih that 1080 TI, 6700k/7700k and 8gb of ram are your bottlenecks.
Yeah, my CPU is watercooled. When I end up building my new system, I am definitely going to get a waterblock for this GPU as well, it NEEDS one. Luckily, EK makes one.
I do agree with you about my bottleneck. With Threadripper coming up and Coffee Lake coming up (but the real chipset is supposed to come out in January...), I am not sure what I want to do.
