abit does not have any stability problems, its great for that purpose, for overclocking the fsb really can't go over 260 fsb at all, im stuck around 254-256 on my winchester 3000+. apparently, at that point the agp / pci lock for some reason stops working and i cannot run 3dapps any higher but i can boot into windows at like 285, but since the agp bus is being overclocked i definately wouldn't recommend it.
