To be honest, number crunching on a GPU is better than a CPU, since GPUs
were designed to number crunch.  Look at the newer CUDA and ATI GPU
cards.  They have 32, 64, 128, 512, or more "cores" or "streams".  There
is a movement to create systems that are GPU based instead of CPU
based.  The gaming systems are almost all GPU based, since they do not
need to run traditional packages that a "home" or business computer
needs to work with.

Well, the Excel vs. Calc speed comparison on the same system [32-bit] is
a different "thing" than making a 64-bit version of LO or a GPU based LO
package.  The difference between Calc and Excel may be the efficiency of
the coding.  There are still a lot of old legacy code in LO that is
being worked on to make it work better and much more efficient.  Just
saying we need to create a 64-bit version of LO to fix the "speed
issues" is not really solving that issue.

As for making LO work with a GPU card, well I would not be surprised
that not too long from now, both Windows and Linux will have a version
that is GPU based.  That is one of the things that would make our
current systems faster without replacing the motherboard or CPU.  Just
buy a newer, faster, GPU for the system.  This is what the gamers do
currently.  The price of these faster GPUs are going down.  For $100, I
could buy a GPU 3 to 4 time faster than one I could buy 2 or 3 years
ago.  The GPU speeds per price is a much better "ratio" than the CPU
speed per price.  You just get more speed or number crunching power for
you money with a GPU card, compared to the CPU/motherboard costs.
