there seems to be a lot of mention of dual processor systems in various forums here. consequently there is a lot of referral to MSI's dual athlon board, but it seems like not many are aware of the others. ASUS just recently announced their athlon dual processor solution, the A7M266-D (AMD760 MPX chipset) As well, Tyan has their Thunder and Tiger series for the dual athlons. I'm not sure how readily available the new ASUS mobo is at the moment, but i'm basing my system around it. Also as a point of interest, Intel has a technology built into their newer P4's (manufactured with the 0.13 micron process) called HyperThreading, which "fools" the motherboard into thinking it's a multiprocessor system, thereby allowing it to function up to 30% faster. HyperThreading is currently DISABLED on the chips by default, and requires that it be turned on through the system bios. so far very few, if any, motherboard bioses support the feature, and Intel is aiming it for the server market more than anything, which means it probably won't show up as an option in any mainstream desktop system boards, but who knows? Of course, if you even manage to enable it, the software you're running has to also support HyperThreading, or you could actually end up with a processor running anywhere from 1 - 10% LESS efficient than before you turned on HyperThreading. It's all very well and technical, but you can read way too much about it on Intel's site somewhere if you feel for it. sea and you.
