Funny I skipped P35 & X38 altogether (except for the asus P5K-VM). The DFI P965-S Dark I have clocks my b3 Quad to 3.3Ghz on air & 3.5Ghz on water. After being dissapointed with DFI's RD600 after so much hype, and both abit & dfi's 680i quad performance I'm not as eager to jump on new chipsets anymore. I'm gonna wait for 780i and Tri SLI.
