<< ...And to add, PC1066 RDRAm when on a 533fsb has latency close to that of PC2100 DDR, and PC1066 with 533fsb will beat any DDR platform. So I say go for a Abit Th7II or P4T-E now (make sure you get clock generators that can go to PC1066). You won't be sorry! >>
Even if it is wiser to go with an existing RAMBUS board such as the P4T-E or TH7II (and I'm not too sure about that), I say wait until May when the 533FSB versions are to be released, because the prices on the old boards will plummet. 😉
