    I'm trying to run Vista 64-bit, through Fusion, on a Mac Pro 2.8 Octo with the factory 2gb of ram and it's horribly slow. I have 1gb allocated to the VM and 1gb for OSX and, without running any other programs, I'm essentially left with about 100kb of ram. Many of my cpu's also show >70% usage.

    I'm ready to buy some more ram, but I'm wondering about how much I really need to get everything to run smoothly. I am on somewhat of a budget so I can't exactly max out.
    My intention is to be able to use Autocad (no major 3d work, but some of the files can get large).

    Thanks for any help.

    The smart buy for a MacPro is a 4 GB kit ( 2 x 2 GB FB-DIMMs)

    Buy from a reputable Mac-aware dealer.

    1. Yes, 1GB for Vista is sub-optimal normally, much less for a big application.
    2. 1GB ain't so great for OS X either.
    3. Vista 32-bit will run a bit faster, and really with no real downside since you're not even close to the 3GB/4GB RAM limits of Vista 32-bit.
