Are all Mac Pros - 64 bit?

[CajunBob]

Sorry, Newbie here.

I'm trying to buy a used mac pro but need a 64 bit machine. Are all Mac Pros 64 bit?
If not, what models are?

Thanks,
Bob

All MPs are 64-bit.

All Mac Pro CPU's are 64-bit, but models 1.1 and 2.1 (2006, 2007) are 32 bit EFI, and can only run 32-bit OSX kernel (but you can still run 64-bit apps within the 32bit kernel)

Thanks for the info.
