Tom IMHO I'd advise against Vista, just read the other posts about it. I think it is a white elephant for design purposes. I got it a few months ago. First off, my SU icon on the desktop wouldn't work, when I clicked on it, it crashed, so I've had to replace it with a file shortcut that just goes to a blank SU file. Some SU plugins won't work with vista either. This is all mentioned in "Win Vista and older ACAD versions" and some other older posts.
I have dual core though and SU seems to run very well.



to people when I mean "you'll be lucky"
