So, are you saying when it comes to serving tons of movie galleries 64bit is the way to go... but for video rendering and compressing Core Duo makes more sense for now?

I don't know that I'd really quantify it that way. If you have a need for >4GB of ram, there is a benefit to using 64 bit processors. Otherwise, I would let performance per watt be the deciding factor. The amount of electricity used by a modern high performance CPU is non-trivial, and all electricity used is ultimately converted to heat, which then requires more electricity for a compressor to move the heat outside and cool your office/datacenter/(bedroom?
)
A core duo processor pulls approx 27 watts. A P4 Xeon processor pulls approx 150 watts. The core duo does about twice as much work as the P4 Xeon.
Intel is going to be releasing a new Xeon chip based on the same technology to improve the performance per watt.
I would personaly prefer a bunch of Core Duo's in a datacenter than a bunch of P4 Xeon's, but there doesn't seem to be any servers that use those chips *yet*.
