that is not an issue. it support up to 1ghz, and there re no higher p3 cpus. anyway who uses slot-1?
i though most use fc-pga witha slotket (i like the iwill one), so the question is what cpu does the slotket support. which is still 1ghz. IMHO it will not support tualatin (0.13 micron low voltage p3) so there is no issue. now if there will be a slotket which will suppport mBGA and low voltage conversion, and asus will make a bios for it, that will be great, you ould potentialy extend the life of your rig with a relatively cheap upgrade (to say a 1.5Ghz p3?)
