AMD 64 or Intel 64?

If there are any Tech Gurus out there that can help me out, much thanks. I just read that Intel came out with their 64 bit cpu. Which of these processors is recommended for gaming. Am i better off sticking with a 32 bit Intel processor with a faster clockrate rather than a 64 bit 3000 with 2.0ghz clock rate. The only applications that I heard of for 64 bit are Windows XP 64, Far Cry, and Unreal Tournament. Is it too soon for applications to take advantage of 64 bit processing?
