People are in a frenzy over the Asus P4T533 board with 32bit RAMBUS, but why? The only difference is you don't have to install it in pairs, but I bet when it is readily available it would be cheaper to buy 2 16bit 126MB sticks than 1 32bit 256MB stick. To top it off, it's slower that the Giga-Byte GA-8IHXP (16bit RAMBUS) in every benchmark except for SANDRA. though not by much
