It'd be more like 3-5FPS at my resolution most likely lol
Seems I got 2130-2160MHz "stable" now, set it to 1062mV locked curve, no unusual "artifacts" in game & no crash for over 2 (almost 3) hours of mostly RT-on play - 493W maximum draw, temps were "acceptable", albeit warmer than I'd prefer, 55C peak core (which makes sense because that's basically the lowest "stock voltage", with a 120MHz OC), mem peak temps in the 52-68C range (Junction got to 74C, so 2-4C higher than with the lower OC, but I'm also running +250 vRAM clock for an evenish 10002MHz effective clock), VRMs were nice & normal at 41-57C. Hopefully the vRAM & such temps will come down a little once I get those lil' heatsinks on the backplate, vertical the thing & strap a fan to them, at the very least, I imagine it'll help a little bit. Having a more detailed idea of what the backside layout of the PCB is helps determine where putting those will help the most.
GPU radiator exhaust temp got up to 40C - with push/pull but the "pull" fans were at 1100RPM - have a feeling I could get the load temp & such lower with a bit higher fan speed (topped out at ~1900RPM on the intake/push fans, those fans can go to 2200), but all those peaks were also with an ambient of 73F before I started cooling it back down in here.
I'll have to do some testing to see what the difference if any is from 2100MHz @ 1025mV to 2130-2160MHz @ 1062mV in terms of FPS at this giganto-resolution, probably not worth the ~5C increase in temps or the extra power draw. But it's nice to know the card could apparently run that all the time, if I wanted it to.
