Yeah, it's the best ocing KT133A board (I prefer Asus A7V133, just because I like Asus), and has is the most feature rich (6 PCI, 3 DIMM's, On-board RAID supporting 0, 1 and 0+1 (A7V133 only has RAID 0)). As far as compatibility, just the SB Live! VIA 686B south bridge issues, but those should be corrected by using the latest BIOS, and the 4-in-1's 4.32 or later.
