Not to mention if you look further back in thread you can see that I posted results from same game with diff settings and the total system results are improving as I optimize the system AKA i'm cpu bottlenecked
Thanks. However, you can be bottlenecked by a component to a certain degree, it doesn't have to be complete. It could also mean, that you start to be seriously gpu bottlenecked at roughly 130fps and BD only reaches this mark with tweaking. To analyze this, you would have to do one of two things:

a) overclock sandy further. if the fps rise (almost) 1:1 with the clock increase, you are indeed cpu bound. If not, there is your limit, that now both cpus hit
b) overclock your 6990. if the fps rise, you are gpu bound.

Sorry, but so far it is not conclusive. Also, is it DX9 or DX11?

Here some results for comparison:

970@4000, gtx 570@800mhz sli: 153.4fps avg

His cpu is arguably slower than a sandy bridge at 4700mhz and he still has more fps, because his gpus are slightly faster (or scale better) than your 6990. So no cpu bottleneck.
