The 8800GTX@ 652|2054 on a E6320@ a mere 3.0GHz-
You sure 652/2054 is stable even in high-end games running with 8xAA, 8xAF? 3dmark2006, for me at least, doesn't represent what current games ask for like STALKER and C&C3 which demand alot from GPUs. I recently tried to run with a higher mem clock (2080) and kept my core @ 670 (675 seems a little unstable) and it would choke in most games within 1-2 minutes. Total system lock. Right now, in all major 3d games 670/2013 seems the most stable in my system.
