Yes, 64 bit should become popular with the release of Vista. I hope it doesnt slow things down with being to heavy needing monster CPU, GPU power. I see a pattern here, ..new OS...new computer hardware..rinse and repeat. Guess thats the way tech is. I too have always built my own computers (been that way since opening my first Atari box to put in new CPU). Just havent seen this amount of tech avalible and lots of people have it, just no support in apps, games. Like AS said, its hard not to find 64 boards, combos and such, and all my friends have had this tech for awhile now(Apple or PC).Long story short, just sounds like an average family car(32bit OS) with a Ferrari engine(64 bit cpu).
