I've been using ATI for years and no problems at all. No instabilities or things like that. Cards I've used so far are the Radeon 9600 Pro, X1650 Pro and HD3400.

We've just got a new laptop that has a ATI HD3400 with 512MB and that thing sure rocks. My old ATI X1650 had a few minor problems with displaying large Poser scenes (over 12 figures in it, not counting the props and such) correctly. It would leave out some of the textures, guess it can't handle everything in view. That problem doesn't occur with normal scenes, only large ones.

The HD3400 works great though, even with larger scenes. Displays everything fine and the opengl preview is much closer to the final render, that's a huge + !

The intel dual core works well with this ATI.

Artwork and 3DToons items, create the perfect place for you toon and other figures!

Due to the childish TOS changes, I'm not allowed to link to my other products outside of Rendo anymore :(

Food for thought.....
