Dont bother? Its funny even with two people of different brands showing proof neither is bottle necking performance, you and others still say no.
There is no way a 8350 is gonna hold any single or dual GPU back, unless of course your talking CPU heavy dependent games or tri/quad fire, then you might have a case.
AMD has done more than just caught up to Intels quad core CPU's. There is this thread, plus multiple reviews where it shows the 8350 outperforming the 3570K in multithreaded apps. Which is most apps nowadays.
Single thread? ya Intel is king no question. Heck I just came from a Intel rig, and I plan on going back depending on how haswell turns out. However, I am kinda annoyed how almost every Intel guy says a FX CPU will bottleneck higher end gpus specifically in crossfire without ever showing a shred of proof.
These two guys have showed such proof and are still in the process of doing so, yet proof seems to not be good enough.
