I just upgraded my cpu to 3.0 ghz and also got a 6800 gt. But to my horror when I run Far cry demo it wigs out BIG TIME. I'm getting huge chunks of black unrenderd space, and after a while, my sound freaks out, I lose all sound and artifacts and colour changes begin to happen. Also some of the special tests on aqaumark3 are freaking out aswell.I have all the newset drivers and updates for everything I have. Painkiller seems fine. Quake3...well thats years old but I thought a system like this would allow me to play far cry and stuff with nice levels of detail? Whats going wrong? Is this a faulty peice of hardware? I don't have long left before I can return it.
