I'm curious what userspace you're all running.  I'm using
xf86-video-intel from git on Feb 4 with 2.6.37 (completely unpatched!)
and my i7-2600 is quite stable.  The only problem I have is that
compiz has hung twice since I got the machine.  In both cases, killall
-9 compiz rescued the system.

Fedora 14's xf86-video-intel didn't work so well (compiz dropped
enough frames that the effects weren't really visible).

I'm single head on DisplayPort.

(Even firefox 4 webgl works nicely.)
