I'm currently running an Asus P3V4X, and it runs pretty well. I'm using a P3700E@1085MHz with a GORB, and very few lockups in Win2K. Your P3700 may or not be able to make it up to 933, if it hasn't come close on any other motherboard. Depends on the processor. But if you've tried it and it works, it will most likely work on the P3V4X. Only thing I don't like about hte P3V4X is only 5 PCI Slots :-(.
My friend has a P2B, running a 300@something, and he says he likes it. But it doesn't support AGP2X, and I don't think it has SoftMenu or osmething like that (I could be wrong). P3V4X has SoftMenu (for overclocking. Quite useful)
