That 64bit is only useful in obscure situations and only for programs which use obscene amounts of ram is nothing more than a myth. Any program natively 64bit will likely work better, and there are more of those every day, and anything that isnt will simply run as a 32bit program. I've been using win7 x64 for a while now as a gamer and except for some things working better and faster I haven't noticed a single (negative) difference from being on 32bit.

As far as not having any native 64bit applications... I think almost all my drivers and most of my applications came in x64.
