I have the 1.2 Duron (along with the ECS K7S5A for $89 at Fry's BA a couple of months ago) and it looked like the bridges were cut, but they weren't recessed, so I suppose it would be easy to overclock. In any case, I put the CPU in my KT133 Asus A7V which tops out at a multiplier of 12.5, so I don't have much incentive to try and overclock it (KT133 doesn't support 133 FSB).
I suspect that most Duron's won't work at 133 FSB unless you change the multiplier down at the same time. With the Morgan core, though, the Duron is as fast as a similarly clocked Athlon-200 and is substantially faster than a Pentium III at the same clock.
Here's a review of the board. The board has a Promise RAID controller, so you can hang 8 IDE devices off it. Four USB ports come with the board with support for two others. I've built a lot of FIC boards and they've been decent workhorses, on the whole. My two main machines are both AT FIC VA-503+.
lchen66666, I might suggest mentioning the store & region in the subject line, since this deal only works in the Bay Area (and maybe other markets where Fry's happens to be hosting the same sale). Why waste folks' time reading about a sale they can't take advantage of (and incite a bunch of "Why don't we have Fry's too" posts)?
