This isn't my opinion (as I don't know enough to have one) but one of my friends strongly dislikes the chipsets for dual Athlons. His opinion may be a bit biased, as his multi-proc boxes are servers, not number crunchers, but that's what he's said. His preference is for ServerWorks or Intel chipsets with Intel processors. There are some numbers here: http://www.scientificweb.de/mathstef3.html with benchmarks for various tests, but it doesn't look like too many dual-proc configurations are tested there. This site: http://www.2cpu.com may prove to have some better resources for you, as well as more current/relevant benchmarks. As for the processor itself, I've only heard that the MP is essentially the same as an XP, just "guaranteed" by AMD to work in a multi-processor setting. I've also heard there were issues with Tyan's first dual-MP mobo, but I would imagine those issues could be attributed to being bleeding-edge and would be resolved by now. my $0.02. Hope they help. -John >>> lxy at cloudnet.com 10/29/02 10:27AM >>> I'm building an uber-number crunching box for a guy. He wants the best in everything, so naturaly I recomended an Athlon MP machine. he had a few choice words to say about the dual MPs, and wanted a single Athlon instead. He wouldn't tell me WHY, other than "I've heard things". Is Athlon MP a good choice? Are there weird issues under various OS's? (this box will be running dual Win2K/Linux). -Brian _______________________________________________ Twin Cities Linux Users Group Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.mn-linux.org/mailman/listinfo/tclug-list -------------- next part -------------- An HTML attachment was scrubbed...
