It is going to take a long while before everything is 64bit.
If you ask me, 64bit is still kind of a "hype" (for the lack of a better word, so mind the quotes). 95% of all programs are still 32bit. You will still have troubles finding decent and correct 64bit drivers for many stuff. Some programs wont even work under 32bit simulation on 64bit machines, etc...
If you have the cash and if you're geeky, buy it by all means. Otherwise, just stick with 32bit for the time being. By the time 64bit has almost completely taken over you would probably already have bought a couple of new PCs anyways... (unless you plan to stick with your PC for like 10 years like me
)...
Vintige FTW! lol
