Nvidia vs. ATI
-
Thanks Rich. I'm also running Nvidia cards currently. 9800GT in my desktop and 9800M GTS Cuda in my laptop. In both cases I use them simply because that's what came with the computer when I bought it prebuilt. The idea of having a PC built to spec opens up a world of choices, which gets one to reading. When you read all over the place that the new ATI HD cards are running circles around Nvidia, it just makes one start to wonder about choices. I guess you're right though, if it ain't broke.... After all CPU cores and memory are what will really count for rendering speeds, at least until Vray GPU hits the streets.

Unfortunately I made a big error on a recent laptop purchase. HP Pavillion with ATI card. SU is very buggy especially when the poly counts grows. Strange display gremlins when using select tool also. Not happy with it one bit.
My advice is stay clear of ATI
Turning off "Fast Feedback" in the Window>Preferences>OpenGL pane might help with the tool gremlins - at least they did with my very old ATI card.
I played it safe with my new computer and bought a Nvidia QuadroFX 1800 card. No problems this far. I don't play games.

I run my ATI HD4850 since over one year now with no issues and heavy SU usage. It performs great with any size of model as far as SU takes it. At work we got Nvidia quadro FX1500 installed on 10 PCs, which cause major problems randomly, especially with SU. But according to all the problems I read about, I would go with Nvidia especially with SU use. I believe that I just may had luck with the decision for an ATI HD4850. Beside it's great performance it was a decision for silence, which was right.

For your works, I thinks that you must also have a look to the nvidia quadrofx 1800 or 3800.
I know that the second one is really expensive, but as you are talking about optimal performance with autodesk softs and renderer (3DS) or good compatibilities with Sketchup, and nearly nothing about games... Professional card are the best. Of course, there is also some FirePRO from ATI, but I think that Nvidia has,for the moment the better place and compatibilities with professional software : bench

I'd go for nVidia. I recently had a pretty decent ATI HD somethingsomething - and I experienced graphical glitches in OpenGL apps. Especially in SU. And that was with updated drivers.
Going back to nVidia and everything is just dandy.

by the way how does one activate hardware acceleration....or is it automatic.?

Window > Preferences > OpenGL -

Window > Preferences > OpenGLSigh... Easy this way - shortly!
When installing, SU will try to guess if your video card is capable of handling OpenGL properly and will activate or not activate HW acceleration accordingly.
You can always override this setting - and some other ones as well - under (Window menu on Windows, SketchUp menu on Mac) > Preferences > OpenGL settings.

I don't see any OpenGL settings on my Macs....

Ah yes, that may be different (but at least preferences are there...)
