it depends on WHY you are stressing it, and what's your objective..

i like to call stable when i can play for hours like 4~5~6 without any problems or artifacts.. that's what i call stable, i really dont give a shi* about furmark/occt gpu/kombustor/etc..

sometimes i use the stress-programs but for 5 mins at top just to check the temps quickly, not an hour or 1 day... only because it's not stable on them doesn't mean that isn't stable on games too. you guys have to agree with me that any kinda of game is definitely less "heavy" than these stress programs.. so why not use a game that is the closest of 100% gpubound to test the overclock? i know this older way, takes more time, surely u will get more bsods, so what? At least you won't be hurting your vga.

some guys "play" furmark .. they have the furmark icon ready on their desktop ..im not saying you or you do it, but surely some do. the super stress abuses the card too much (it was made to do it), gpu and all components do suffer a lot when the stress is rolling mainly without pauses, it's like you contributing to kill your own vga minute by minute..

again, and just to let clear, that's MY point of view.
