Overclock New iMac [Please Read]

[nlr]

Well, theoretically that chip should go above 900MHz because it's based on desktop 5770 which has stock clock of 850MHz. That might run too hot because desktop 5770 is rated at 108W. I would say 725-750MHz should work without issues. That's little more than 5870 and already 20% increase from 625MHz (stock clock).

Maybe someone can try it for us? I'm not that familiar with GPU OCing, especially mobility chips but that chip does have a lot potential.

I would love to see someone overclock the graphics card so we can see the potential of the iMac's gaming performance and see what games it can run maxed out?
