...you try raising it by 12%? Set your FSB to 112 in your BIOS and see how it runs. 112Mhz is me rule of thumb in OCing since it was the only weird divider I had on an old crap mobo, but I've found it to be a real mild one heat-wise while still giving a nice zippy performance boost.

Anything much beyond that and you'll probably want to increase your cooling, but the stock intel cooling really is pretty good and shouldn't have a problem with it. (Usual disclaimers about me not being responsible for you mucking up your rig based on me suggestions, but I feel pretty comfortable recomending ya try it.

)
BTW- On drivers? Go with the Omegadrive's first, they're a welcome breath of fresh air after some driver problems.

Some people have a problem with the idea of a custom tweaked driver set is the only reason I recomended the ATI one's over his. For stability & image quality, I still think Omegadrive can't be beat. (I haven't played around enough with these new cats yet to recomend them over the O-man's even though they look good so far.)
