Vista 64x and 86x

I just recieved a copy of Vista Ultimate, not knowing what to expect at all.
I knew a little, such as this operating system does support dual core and 64x
processors...

My problem is, I came to understand that Vista Ultimate has everything,
including being able to support both 86x and 64x, there being some option
during the install.

So, basically...am I completely wrong, or did I miss something, OR did I
just get the wrong version of Vista?

Also, does Vista have all the same compatability problems that WIN64 had? I
know I lost my webcam, printer, most of my video options, etc...

Thanks!
