I think the biggest area that 64-bit really pays off is in the high-end server
arena where greater memory capacities are called for. Otherwise, there just
aren't any substantial performance gains in running an x86_64 chip in 64-bit
mode. Where the AMD64's are cool is in their use of hypertransport. I really
have to wonder why Intel hasn't started using it, especially with their
multicore processors. (No, it's not an AMD specific technology)

Thanks for the inputs from everyone. I'm glad to have it confirmed by others and
I wasn't having delusions. Unfortunately, I think I ended up buying another gig
of memory unnecessarily now that I've gone back to regular x86 Ubuntu. Too bad I
don't have any time to game these days. I bet BF2/2142 would run better now that
I've got 2GB.
