Ah ok thanks BTW anyone care to post some very high 4xAA 1920x1200 Crysis benchs with oc 5870/5870s? thanks in advance.

Here you go. This is with with adaptive AA on and 8x AF as well. Works pretty well if I must say so. 1000/1300 on the clocks.

I've found that on my Sapphire 5850, RTHDRIBL causes lockups/artifacting/instability at lower clock/higher voltages than any other tests I've tried (inlcuding FurMark).

For those with 1GHz+ GPU OCs, what voltage do you need for RTHDRIBL stability (full-screen/maximized, maximum details)?

Mine does fine through there at even 1.2v for 1ghz. Oddly enough what made me go to 1.225v was the Stalker: CS benchmark. It would lockup at 1.2v, but went perfectly smooth at 1.225v. Might want to give it a go after you get RTHDRIBL stable.
