So i've been testing my brand new 7970 that you guy's have recommended me a couple mouths back, and so far i've been good. Have it with a mild OC at 1050/1500 (from stock 925/1375) and so far only crysis 1 has been giving me problems, when i recently decided to play it again. With this OC i run bf3 on max settings for long play sessions (8 hours+) crysis 3, both uniengine heaven and valley, civ 5 and everything i throw at her, even furmark. But crysis 1 starts to give artifacts near the water, and then sometimes the pc reboots. If i use 925/1375 all is well. No artifacts, no reboot. I can just use stock setings for only this game game no prob, but find it strange that only crysis 1 is giving me trouble, and crysis 3 is not.... So i just thoght i stopped by here to tell you guy's how everything is going, and share this little curiosity. Have any of you guy's had a similar issue? Thx's in advance gurus!
