64 bit Vista

So here I am realizing 5 months after owning a core 2 duo that its 64 bit.  and while i run gentoo on my laptop and server, i still require windows for my main desktop.  So my question is, will I notice a difference with 64bit apps (mainly video encoding), or should i just not care?

Are you a faggot, or just pretending?
Why THE FUCK would you use that piece of shit Vista?
Get Windows XP 64 bit edition and the fuck out of here. And only do if you want to suffer from poor device driver support.
What I'm saying is that you, >>1, should stick with today's special: Windows 2000 Professional.
