I recently tried to run with a higher mem clock (2080) and kept my core @ 670 (675 seems a little unstable) and it would choke in most games within 1-2 minutes. Total system lock. Right now, in all major 3d games 670/2013 seems the most stable in my system.
Yes. I have played hours on end in "Oblivion" with HDR+AA active and the highest possible quality settings. I only game @ 1680x though. My card is cooled with a Thermalright HR03 Plus and a 92mm Panaflo H1A fan. Idle is 45C and load after hours of "Oblivion" = 55C. That's under ambient conditions of 21C. Naturally, higher ambients will add a few C. That cooler is fantastic
I've also tested for hours with ATiTool's stress test that has my card pumping out well over 1300FPS. If it's unstable it has yet to show in any game or circumstance.
Hardware is luck of the draw. Some cards may clock higher than others and I am certain temps are not an issue.
