also, Nvdia cards seem stabler than ATI, PC is much more solid than MAC.
See my tutorial in signature on import optimization as they can take an assload of resources.

Totally disagree that PC is much more solid than a Mac.

I have been using Vue on a 2008 Mac Pro since Vue 7 and although I duel-boot into Windows 7 Ultimate 64bit for heavy scenes, most of my work is done fully inside the Mac OS. I can tell you that I have had very little problems at all with any major crashes with Vue 7 or 8 on the Mac and it has been stable in that regard. Right now, there are some things different between the Mac and PC version, but once the 64 bit Vue 8 is released which they are working on it will be a moot point.

I would advise looking at the threads here as suggested and seeing if anything helps. Also, while nVidia seems to be more common, I know at least two people using ATI 2890 graphic cards with no issues.
