Yawno. Unless it's cheap it will no doubt get its ass handed to it by the Saber and Crosshair. There's just no beating those boards, apart from on price.
MSI don't exactly have a good track record with AMD boards either, with many of their boards bursting into flames when running an 8 core OC.
All I can say is where the fudge are the MATX boards. If you're listening, MSI, I can absolutely promise you that a decent 6 or 8 phase board that's MATX and has a decent heatsink on the fets would sell by the bucketload.
Asrock have just released a half decent looking MATX board for AM3+ and that's where the money is. Mid range PCs don't need to be huge and because they're all ATX people have to buy a full sized case which usually works out much dearer than a MATX.
Sort it out !!!
