Created an account to post this score! Just got a brand new EVGA GeForce GTX 1080 Ti SC2 GAMING, and have been tweaking it for a week.
CPU: i7-4790K @ 4.4Ghz
GPU: 1080Ti @ 2012/1600
Score: 6213
Used EVGA Precision X OC to dial in the 100% voltage, 120% power target, 90C temp target (priority), +26MHz GPU clock offset and then the massive +900Mhz Mem clock offset. I think I got lucky with a pretty good GPU core but an outstanding set of memory. No artifacts at all. Air cooled.
Pretty excited to make the top 10! (#6 at time of post). I don't think i can push it higher and higher core clocks mean drastically lower memory clocks which drops the score quite a bit.
