Well I did a really weak overclock (my pump had failed on me, and I was using my old zalman cp9500 for a while, but I finally fixed it) of 3.15ghz and ran these guys in cf and I managed a score of just under 18k. So it appears that this CF setup is definately dependant on CPU speeds. Gonna take it up to 3.6 and see what I can get. Still not convinced that CF is performing how it should be though.
I am liking these cards regardless. In AOC I get pretty sexy fps. =)
