In my experience, 32-bit systems are about 10% slower than 64-bit
systems. Unless you are benchmarking, this is not really noticeable.
Also 64-bit applications are about 10% larger. In today's HW
environment, that is really a non-factor.
Of course the big advantage for 64-bit systems is when you have more
than 4G RAM or need to manipulate a file that is larger than 4G.

I think even Windows went 32-bits a long time ago.
