Is the Pentium III with the Tualatin core only for dual processor computing? I have a PCChips motherboard (model m791g v1.0a) that's supposed to be able to use the Pentium III Tualatin up to 1.4Ghz(link: http://www.pcchips.com.tw/PCCWeb/Pr...3&LanID=0&DetailID=248&DetailName=CPU Support). I actually bought one for like $150 and it didn't work. So what do you think? Did I shoot too high? Should I try a lower 2.66Ghz Tualatin CPU instead?
