64 is closer then you think.
drivers for newwer hardware are in both 64 and 32bit mode.
The reason being is the 32 bit core memory cap (3 gigs). This cap is shared with your video card.
So for the most part your limited to 2 gigs of ram and your vid card.

bother to read the
title, much less the link.
We're talking about a 64 core
processor, not the 64 bit OS (which I agree, is goign to be teh standard
very soon).
That said, isn't the 32 bit memory cap
four gigs? Otherwise, it'd be awfully hard to manage the 3 gigs most people recommend for Vista gaming (though you are right that its shared with your video card).
I'm quite sure its 4 gigs memory, just like an application is size-limited to 4 gigs (if it tries to go over 2 gigs it crashes because half of that is allocated to the kernel for stuff like drivers, unless you've tweaked your bootup settings).
