Thanks for answers. But 1) it's Core i5 (quad core), RAM 8G (maybe some revise of 5110) 2) I know, it could work at least twice faster than Samsung notebook with Core 2 Duo, 512MB free RAM, 256MB internal graphics on rendering cases. Desktop is not an option, as also custom machine - not 'cause coffee shop (it's not an option too... Russia it is XD).
Games, from other side, are always rendering something, too - just in real time with some significant simplifies in ways of processing video. And they are flying at max settings (although I hadn't tried somewhat like Crysis).
From 3rd side, Studio Max uses just the same way as games for scene and model prototyping - as uses other software. The version I have isn't glitching on above mentioned Samsung note (one of R45+ variants).
I have a suspicion, that drivers are guilty - but are the alternative ones good enough? And do they exist at all? (hadn't googled it yet
I believe there should be a way to force videocard to work correctly, I just don't know, how.
P.S. About 'workhorse' again. I didn't mentioned full workstation of 3d designer, I just need something that can smoothly visualize assamblies with 100-500 components. It's not too high, for example, that is little walker bot assembly, or half of internal combustion engine.
