Soltek definately has two thumbs up IMO.
I first used one of their earlier Nforce2 boards in a friend's PC, and was so impressed, I got one for myself (ended up being a better revision too!).
I've used three different models of Soltek's Nforce2 boards (unfortunately NOT the one you mentioned), even one with the IGP (integrated graphics). I'm equally impressed with all three, so as a brand, I can definately give Soltek a recommendation.
OTOH, I know little about the board you are considering for purchase. What I can tell you, is that the BIOS's for these boards are based highly on Nvidia's reference BIOS, which includes a suite of overclocking options. In the three Soltek boards I have experience with, the BIOS options have not differed from Nvidia's reference design, which leads me to believe the board in question, has all the overclocking features you are looking for.
Try loading the online manual for the said board, a lot of times it explains the BIOS in detail, in which you would look for the options you need.
Why noone recommends the Soltek boards are beyond me. I don't see very many boards mentioned besides the typical Asus and Abit varaties, but rest assured, there is quality and value present in other brands as well.
Hope this helps!
