Only one i have owned is the ASUS P6X58D-E which is one of the latest boards in the X58 line up, and it's an amazing board really. 32nm 6 core support. USB 3.0 16+2 phase VRM.. which is just batshit insane.. 3-way SLi and Quad fire supported.. I was able to maintain a Bclk of 210 without any other tweaks such as PCI-E OC or other work arounds to maintain a stable Bclk! Supports newer memory.. running 1600mhz Kingston Hyper X Fury Blue's (1.5v CL10 rated) had them all the way up to 2000mhz on 1.7v !
