EVGA - Period. Look at my profile & configuration. I had to RMA 10 GA-X58A-UD3R (rev 2) MOBOs, I kept 1 to mess with for a Hackintosh rig, and replaced the UD3Rs with ASUS P6X58D-E for pseudo Workstations for my office.
The GA-X58A-UD3R is great on paper ONLY, but if you add a SSD + RAID ~ guaranteed BSOD or Unstable at any moment Shutdown. It's on-board poorly powered controller look pretty, but aren't up to the task and cannot support as advertised. The P6X58D-E only lacks a I/O eSATA, but beats the P6X58D-E beats the UD3R in most all tests.
