Ok, what I have is a Gigabyte 6BXC PCB 1.9. Latest BIOS update is from August 2000 (or 2001, doesn't stand there) and mentions that it makes the board (only later versions) compatible to FC-PGA. At the moment a Celeron 366 sits on an Abit SlotKET-III (1.3V to 3.5V, FC-PGA etc.). Can I now just build in a Tulatin Celeron? Only setting down the voltage to either 1.4 or 1.45 or 1.5? Or would it be better putting in a PIII? I mean voltage is no problem, a bit less or more than the wanted 1.475V should make no problems. So the only problem which I see is the new VRM specifications... That means the MB has to keep the voltage more constant, right? The PowerLeap adapter seems not to be compatible with my board... BIOS hang-up... does that means I can give my Tulatin dreams up? What CPU would give me the best price/performance ratio? I have a GF2MX in my system, a Golden Orb (would there be heat problems with any possible CPU?), Windows XP and 192 MB RAM. I am mainly doing video editing (capturing etc.), gaming and running my small webserver with my machine (beside normal things like surfing, mp3 etc.). Ok, I think I'm writing too much 
thx!
