Soltek SL-K8TPro-939 is the most stable and fastest at stock speeds
Neo2 has the most features and overclocks the best.
ASUS A8V is a high quality board, the price is intermediate between the Soltek and the neo2.
Not too sure about the EPoX and the ABIT.
I'd go for the soltek, unless you plan to overclock. If you do, then go for the ASUS or the Neo2, but I've heard some bad things about the Neo2 (NB fan loud, problems with the board...etc).
