Eh, good point I forgot about that :-)

I didn't say there was _no_ performance gain I said I didn't think it was worth while.
What I really should have written with that comment was that
in my humble opinion, without the mother load of addressable memory and the performance benefit from sheer resource volume (amount of physical memory, cpu and bus speeds, etc).
The potential for headaches probably outweighs the probable benefits offered by the typical desktop :-)
My desktops dual core chip is X86-64, not counting a lone Motorola 6809-family chip it is the first and only one I've had that isn't purely X86. I'm quite interested to see 64-Bit computing become the norm, especially the implications of porting some software... But have yet to see sufficient advantage w/o exceeding the limits of existing 32-Bit systems.
