Re: GTX 280 screeching...
Vsync did not work for me. I remember my GTX would create the same sort of noise, only not as loud, in 3Dmark03 when the FPS were high. This is constant, and even happens in Crysis when the FPS are in the 30's. The problem is how loud it is, like I said, I can hear it over all of my case fans at their highest settings and with my headset on in-game. I think this is the same problem thats being mentioned here, it's just much more pronounced, which is why I cant just ignore it like I would usually.
