I used to be an Abit cheerleader too, untill I bought the KG-7 RAID which totally blew my nerves. Blue screens, stuttering, corrupt data - you name it. It wouldn't overclock past 138Mhz FSB without crashing..
I returned it and took MSI K7266 Pro-2 RU instead. Yeah.. Same ddr-ram sticks now overclock to 166Mhz with _default voltage_ unbelievable.
All that aside, I think Epox 8KHA+ is still the king of the hill performance wise even after the introduction of KR7.
