I'm in a similar boat. I was all set to go Intel, but the release of the 3000+ 64 is causing me to hesitate, as it isn't a whole lot more than what I was looking at Intel wise (< 100). I want to keep my 512 MB Samsung PC2700 CL2, as well as my 512MB Corsair PC2700 CL2 in whatever I buy--I'm assuming that since the memory controller on the CPU supports (or so they say) PC2700, I should be safe using these sticks with pretty much any of these mainboards....is this is a bad assumption to make? I've seen some folks building 64 systems with that MSI board.
