64-bit allows you to address more memory (beyond the 3 gig 'barrier') so you could probably make more complex scenes...

Each computer instruction is twice as long, so you might see some increase in speed...

but, as with anything else, you're really limited by the slowest component, so you'd have to know on a case-by-case basis...
