I just recently went to a dual CPU system. I just built a Tyan K7 Thunder with 2 x 1.2 AthlonMP's, 1GB ECC REG. PC2100 Crucial, Adaptec 3200S with 4 x Cheeath X15's RAID 0/1, and a GeFDorce 3. It is the most stable AMD board that I have ever used and the performance is incredible. The Tyan Dual Socket A board is great, a little tricky to set up, nut once you hjave it up and running, it is a awesome board. The price isn't to bad either. If you do choose the Tyan K7, Don't use the NMB 460watt power supply, it is causing all kinds of problems with this system. PC Power & Cooling makes a 450watt power supply with the 24pin & 8pin power leads needed for the Tyan K7, it is a bit more expensive but worth the extra money. You may be waiting awhile for any other Dual Socket A boards to come out, MSI has problems from trying to use the Via 686B Southbridge. I haven't heard a word about any other manufacturers Dual Socket A boards.
