nevermind, was snooping around AMD's website and saw this which was very interesting:
"AMD64 technology improves performance for PC-based games by evolving industry-standard technology from a 32- to a 64-bit architecture. 64-bit computing allows video games to process and access more data than is possible with 32-bit computing enabling a more realistic experience with faster frame rates and larger, more immersive worlds. AMD64 technology is an industry-standard approach to 64-bit technology that combines innovation, simplicity, and foresight to deliver the next generation of gaming performance today. Future releases of Far Cry will contain a beta version optimized for AMD64 platforms. AMD64 technology gives you the advantages of 64-bit computing while preserving compatibility with existing 32-bit software so you can run the 32-bit version of Far Cry now and upgrade to the version optimized for AMD64 technology when it becomes available."
So basically its safe to buy Far Cry now and when the 64 bit version is released, you will be able to upgrade (better be for free) and you will take the advantages of the 64 bit program. Kick A$$
