Cool.. Will have to do some trial and error now. Got the new(used) gpu today and installed and tested. So far it is a decent gain in performance (20-50fps depending on the game).

Had to bump it down to just 2x2gb for the sli to work, but was able to run the ram at 1066 vs 800. Hopefully be able to squeeze a little more out now.

Thanks for all the help!
