Chris I will have you know that I run a software company. We are very much
into distributed processing. All I need is 127 more Commodore 64's strung
together and I will have all the power of an iPhone.

Michael:

Trevor answered your question with knowledge, and good advice.  I certainly 
can't add anything to his reply.

Going beyond his reply, the issue is first do you have all the 64 bit 
drivers you need?  If you do, then maybe going to the 8 gigs of RAM, 
installed to take the best advantage of their capabilities, as Trevor 
explained, might be a good idea.  Another option, going back to the very 
early days, is to use some of that RAM as a virtual disk, and using that 
virtual disk as the "disk" to load  your program's executables on to.  A 
ramdisk is the usual name, and there are a number of these available.  What 
they do is provide a "disk" that's an order of magnitude faster than the 
harddrives, for the executable to work from.

In times past, we used to load our workstation executables onto a ramdisk, 
and attain near Cray speeds.  But that was with pretty esoteric machines, 
and software.  Doing image analysis from sat data, and geosat data. Huge 
data sets, and people yelling for answers "right now!".

I would think that a ramdisk may be of help... possibly.  But for the best 
performance, take a look at the new Intel i7 CPUs.  These are the next 
generation of CPUs, and have been designed to handle graphics, video, and 
other "large data set" applications.  I think you would be much better off 
by moving to "the next level", instead of trying to squeeze the very last 
erg of performance out of an already over-mature hardware platform like we 
have now with the current main stream Intel and AMD X2, and CoreDuo systems.

On the other hand, those abaci (abacus-es?) can really calculate!! Just ask 
Larry, and MD!
