Is there any link to download  64-Bit windows binaries?

The 32 bit binaries work on both 32 and 64 bit windows.

And there's no real advantage to running the 64-bit version on Linux. It doesn't run any faster really.

It should really. There are more registers available, guaranteed support of SSE instructions, etc. that would improve performance. I'll come back with data when I get around to building it.

Oh yeah, more registers. That's true, it might matter.

I don't know why we don't have an x64 build.

I was going to try creating one but Satoshi pointed out that the 32 bit windows one will work for everyone.. the only reason we need a 64 bit linux one is because not everyone has a multilib system that can use the 32 bit one.  The only difference between building a normal 32 bit version and a 64 bit version is that the 64 bit one will use more memory.  The Mac OS version is both 32 and 64 bit, the system selects the proper version automatically when you start the app.

It does run faster. I've tried both the 32 and 64 bit version on Linux using the same system. You'll see about a 5% to 10% increase in speed on the 64 bit version.

Maybe not much, but every little bit helps.
