  1. What the pro's and cons of Vista 64 bit and 32 bit.

    The system is a Asus M2A-MVP with a Athlon 64 X2 Dual core 6400+ CPU
    Running 4 GB of Kingston Ram.
    Also has a Sapphire 512 Video card with fire capabilities as well as the MoBo.
    Creative 7.1 Sound card, 750w PSU. Overall. Pretty good machine.

    in my opinion, these were the biggest factors

    32 bit
    *picks up 4gb of ram (which I had)
    *more applications are compatible

    64 bit
    *picks up 8gb of ram (which I didn't have)
    *I heard lots of complaints of program incompatibility (especially Vista64)

    One day I'm sure I'll have a 64 bit OS, but for now I am happy with 32bit. I really don't see the need for it yet

    64 bit OS's can register more RAM so it will make full use of your 4GB.

    Programs that need to install drivers etc need a 64 bit version, e.g. anti-virus programs

    Otherwise most programs run the same on a 64 bit OS as a 32 bit, as far as I know.

    There's no advantage for me upgrading to a 64 bit OS (plus I can't) because I only have 1GB of RAM and an old Athlon XP-M CPU (single core, 32 bit) so I haven ever used a 64 bit OS. Just so you know of my personal experience with 64 bit ;)

    Do you know if this the correct way to calculate it or not?

    2^32nd power = 4,294,967,296 (4.294 Gigs) recognized by 32bit OS

    That sounds about right and I have seen that on TS somewhere before but I can't remember what thread it was, it was a while ago now.

    That would mean 4,294,967,296 places (bytes) recognized by a 32 bit OS and that 4GB has to include graphics memory and the page file if I remember correctly.

    (4,294,967,296 / 1,024 * 2 = 4096MB = 4GB)

    I think you are right about the graphics and pagefile. I forgot about that

    Only good reason to use an x64 OS is the use of 4GBs of memory or more since and x86 OS only reads about 3.25GB which isn't a bad thing.
