I would be willing to believe this is generally true, Were they close enough that a PII-300 would overcome the PPro? The PII will continue to get faster, the PPro is probably frozen @ 200mHz. ps. I'm not saying one or the other is necessarily the way to go at this point in time, there just is not enough info to take a stand yet! I'm just "devil's advocating" a little... -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD
