Well what has work for me (i'am not nearly as good at overclocking as most the people on this board are) would be to add one more video card . It can help out to a point if you can not clock your cpu as high as the other guys. I do think the 3 4870 set-up is better than 2 4870x2 are and 4870x2 + 4780 . You also need the NB in the 2600 + range .I made my 22,137 point run with my 3850s @2700+ NB clock and the red ring on in AOD . Dam one more thing i also had to change over to 32-bit vista as well (help with my cpu overclocks).
