I was given a server motherboard with a dual Xeon E5-2660 and now I am planning to build a gaming rig. I figured if I could use the server motherboard and I could save some cash and spend it on a better gpu. My question is that will dual Xeon E5-2660 with 32 GB DDR3 1600 MHz ram bottleneck a 1070,1080 or even a 1080 ti? If it does bottleneck what is the best cpu combo with a 1070?
