I don't think so. In the Open Source world, most projects are still 32-bit
centric, regardless of how many years the products have been supported on
64-bit platforms.
What application were you thinking of that takes full advantage of 64-bit,
making the 64-bit application much significantly faster than the 32-bit
application? The only area I am aware of, is video processing.
It's often a surprise to people that an upgrade to 64-bit, regardless of
CPU architecture, too often ends up slower, rather than faster.
Cheers,
