This was a fun build. My first one with SLI. I had initial concerns with the type of cooling (air vs. liquid) but the GPU temps idle at about 60c and level out at about 72c when playing GTA V (at 60fps, max settings). My choice of PSU was not the best, but power consumption was running at 70% according to GPUz while playing GTA.
Not a big fan of Windows 10 as a platform for playing games, but it works.
