eazyMoney - You've got it backwards. There is only one SMP Athlon board in development, but it is by Tyan. The Tyan Thunder K7 is 64bit PCI x5, DDR RAM x4, Ultra 160 SCSI onboard, 4Mb ATI Rage onboard, AGP Pro 4X slot, and dual Socket 462. Retail price is estimated at around 300$ US. There is no 'consumer board' planned, and 64bit PCI is a native feature on AMD-760MP, so pulling that would be just plain dumb. Cost reduction would be minimal.
MiseryQ - You *are* being facetious, right? Single apps are almost always single threaded. Games are pretty much always single threaded. Running a dedicated server and a local client forces SMP use fairly well, though, at least at LAN parties.
Dual Durons is going to be disappointing. I've been invited to several AMD shows where the 760MP was demoed, and I finally got the AMD rep to throw in two Duron 800s set for 6x133. Performance, even on properly multithreaded apps, was only about 1.25-1.5X single CPU scores, while dual Tbirds managed almost a full doubling of the single CPU scores. Duron's small fast cache works well in single cpu boxes, especially with the EV6 DDR bus to feed it. In SMP boxen, even the EV6 can't overcome the fact that the system DDR ram has to feed TWO cpus. Only the Tbird's larger cache lets it keep rolling strong.
