Has nothing to do with Vista or XP.
Has to do with being 32 or 64 bits.
Any 32 bit OS will only support 4gb total, including your vga mem.
Any 64 bit OS will support 17.2 billion gb. Yes, BILLION.
A 64 bit OS can do whatever a 32 OS can do, only better, including hardware usage.
I don't see ANY reason why to stick with a 32 bit OS.
I have a computer in the living room to run blu-ray movies I download. The computer is plugged into a Sony Bravia 40", which is 1920x1080 resolution. The sound is 5.1. When I first tried out, it had Vista 32 installed. The video sometimes would get choppy, and the audio was absolutly choppy, you couldnt distinguish a word. I thought I would need a faster processor and more ram, but after installing Vista 64 in the same computer, it runs all the movies and encodes audio 5.1 on-the-fly like a charm, with the processor usage always below 25%. Same computer, only different OS.
If the new SH5 can take advantage of a 64 bit OS (and probably will), and if you have a 32 bit OS, any software you install won't be able to use the 64 bit capability of your processor, hence not running at full cpu capacity. What's the purpose on buying a V8 if you will disable 4 cilynders as soon as you get home?
