get either theyll both perform the same. tech just hasnt enabled 667 to use itself better than 533.
...Not sure where you got that information, but on large-move memory operations and high-bandwidth situations, there's a clear difference. After all, the base rate is 66MHz higher and both the CPU and system memory bus in the macbook, iMac as well as other Intel 9x5 chipset systems, exceeds that of the RAM -- so the RAM can become a bottleneck under intensive CPU <-> RAM operations. Not to mention the 667MHz / 333MHz base, syncs properly with the CPU bus and helps releive cache load in those memory intensive tasks.
Running Word, Xcel, Safari, Mail, or just playing back movies on YouTube won't stress your system and you'll never notice a difference or care. Video encoding/editing, 3D rendering, large database sorts, etc... The difference is apparent.
Either way, not buying the 667MHz is somewhat foolish based on price alone... It's the same price, if not cheaper as it's currently produced in higher volume due to demand.
I'm getting dejavu typing this... Probably because the net was riddled with these same forms of discussions last time around with PC-2700 vs. PC-3200 DDR.
