Lil update. It came today. Hooked her up, sli went great. I read online that even if this was clocked differently the system would have adjusted to the lower clock speed on the faster card.
I did also notice that they changed the words enable sli in nvidia control panel to maximize 3d performance. Not sure if that is correct, but when i click maximize 3d performance the sli ticket pops up under my cards in the control panel.
There are 3 settings for physx, now im debating throwing in a 9500 gt for a physx card, but for th time being i left it on auto. There was the options for cpu, gpu1 gpu2. Anyone think i should change it?
