"This is mainly why you need the Nvidia card, because GL works best with this card." Sorry to kill an old urban legend, but I've learned (at my dear monetary expense) that OpenGL support IN POSER (mind me, I'm not speaking of games or other 3d apps) is VERY BAD if compared with even a relatively "old" Radeon 9800 Pro video card. I've thrown away 250 bucks for a geFarce 6800 line card only to regret my decision and putting back in the PC my trusty ATI one...
