I just built a Boinc rig using a MSI platinum SLI X58 board, £80 from a certain auction site. I flashed to latest BIOS and stuck an i7 980X which cost me £360, also from an auction site. The MSI board performs well, going into the cell menu for overclocking does seems a bit of a time warp compare to my ASUS X79 rig but overclocking was simple enough. One thing that was annoying was the MSI live update feature refused to work saying I had the latest BIOS version, when clearly, I didn't. I don't know what your budget is but there are plenty of cheap X58 mobo out there if want to really get the most bang for your buck.
