In my opinion I would pick an Iwill motherboard. KK266, KK266-R,KA226,KA266-R,or the new KK266+. All support up to 1.5GHZ and higher, plus the ones with the -R, have built in RAID. How can you beat that? I'm using a KA266-R, and I have had not a single problem with it, also it was cheap! The most expensive board was the KA266-R for $145, and the cheapest was the KK266 for $110. The KA's take DDR, and the KK take PC133 SDRAM. One thing you can beat is the built-in 4.1 sound, and the new KK266+ has built in 5.1 sound! But of course, this is only MY opinion.
