software recommendation - Correct Ubuntu version for Intel i5 PC?

I downloaded this ISO image ubuntu-11.04-desktop-amd64.iso to install on my PC later. My PC's CPU is an Intel i5, do I have the correct ISO image?

Thanks in advance.

As for the CPU, your decision is right. Core i5 is a 64 bit capable processor, which is the amd64 version (please note that the amd is nothing to do with your CPU).
