I know Vista is not a necessity right now, but the inner-geek in me really wants to build a system with Vista installed.
I've decided to get an OEM copy of Vista Ultimate along with a new Sata HDD and do a dual-boot system along with a fresh installation of my current OS (XP MCE).
Now my question is - is it really worth getting the 64bit version over the 32bit version of Ultimate (see <-- for my current system spec)?
