'nother vote for SiS, I have a P4S333 and a 1.6a at 2320mhz 145fsb 290mhz memory ddr speed, I installed the motherboard on a system with an existing winxp install and winxp didnt even blink, it just installed all the motherboard devices and didnt even ask for a cd 🙂
It is a great combo, the P4 1.6a SiS chip and DDR memory, when I get my Geforce4 Ti 4600 next week I might need to chain my computer down so it doesnt shoot into orbit 😀
