I think the only difference between this version and the ultra is that the ultra is dual channel. Supposedly, for AMDs, dual channel doesn't make a whole lot of difference. I just finished building with this motherboard, and I haven't had any problems with it. I ran SiSandra on it for about 3 hours and spent about 2 hours encoding some stuff with TMPGenc without any problems. I didn't do a 24 hour stress test with Prime95, but that's because my fans are too loud and would disturb my sleep. The bios has overclocking options: access to the FSB, access to the multipliers, etc... I haven't overclocked because I'm not big on overclocking... it takes too much time to change settings, test stability, etc...
