I've updated for the EVGA 750 supernova, was a pain but it works well. However, whenever i turn on MSI afterburner my screen goes green again and i have to uninstall it in safe mode to work. I guess it's because i asked MSI to up the voltage of the GFX by 800 mv if i remember correctly (maybe it was too much for my Gigabyte GHZ edition ?). I'll try and see if i still have the display driver thingie or not.
You cant up the voltage by 800mv, that would be completely insane. And Afterburner limits you on how much the voltage can be raised anyway to keep things within an Nvidia specified safe margin. Speaking of, I thought all the 7xx series was voltage locked anyway other than the Titan and Titan Blacks... Maybe your system is freaking out because of trying to adjust the voltage?
It might be a possibility indeed. Also i think it's still a driver problem or something, HOTS still crash when at max but not at med. I did a stress test however and it worked fine (and hots is not the game that'll stress my card). Also, the other game that crashes is also when there's some special effect i guess (just like hots crash when spell madness happens). Probably a loop in nvidia's driver ? Even with the older ones it happens tho. Edit : my EVGA supernova made me gain 15+ FPS when i end a turn in Total War Attila tho \0/ as the Antec was stuttering like a dying mouse and my halogens were flickering before lol.
