Linux drivers aren't always the most polished, either. The only time I've seen such behavior was in a dual PII system, and the problem was traced to a network card (though we went through 3 card types before we found one that was stable with the Dual Intel system). Our dual processor Athlons continue to be the most reliable and trouble free systems we've ever installed (though the oldest are still pretty new). We're doing development in Visual Studio .Net on these systems and they are rock solid despite the use of beta development tools. We have systems using both the onboard IDE and card based 2940UW SCSI adapters (we've been buying Tiger based, not Thunder based systems). We've used various NICs and sound cards, mostly Matrox Dual Head video cards and haven't had a single "issue" to date. Not one - we've not yet had to download a single driver, we've never had to update any bioses, no issues, period. These have been really great systems for us, so far. The most recent dual processor systems we've bought are going into our visualization lab and some are using high end video cards - so I'll let you know how those work out once they've been running for a while. We had a heck of a time with drivers for some dual processor PIII systems we installed last year. They were particularly fussy with AGP drivers and it took 6 months to get them to be stable development systems. Our SMP Athlons have been flawless from day one, all necessary drivers were on the CD that came with the system - and they cost less and perform better than Intel based SMP systems. We have site licenses from Microsoft for the OS and Office and a pretty comprehensive configuration requirement for security and compatibility so we generally buy systems from a VAR with the hardware pre-built then have staff set them up. The trouble-free process of setting up the SMP Athlon systems has been noted and appreciated by our systems people - as has the stability of the systems.
