Seeing as how the 64's are out and the AthlonXP proccessors are near the end of there lifetime, this chipset may come a little late for VIA.
"Overall, the KT600 chipset is a welcome addition to the current Athlon XP line of chipsets. With the additional value of the included Serial ATA and RAID support as well as finally having support for the 400 MHz FSB Athlon XP 3200+ processor, VIA may have a success on their hands. However, it isnÂ’t all roses for them quite yet. The memory problems we have discussed are easily an effect of the chipset itself, and whether or not the manufacturers can keep stability high will decide if enthusiasts will grab up the board. And, not to mention, the Athlon XP line of processors does have a time limit to its life now, and the chances of VIA making it big with the KT600 diminish with each passing month."
