[Chimera-users] Quadro versus GTX graphic cards

The quadro cards have had many more graphics driver bugs than the much more widely used gtx cards.  For example, the current quadro driver on Windows has a power management setting default value (save energy) that causes 30 second chimera freezes when picking atoms in large molecules.  Also the quadro cards are usually slower at rendering even when they work.

The only reason to use a quadro card is if it is needed for using stereo glasses.  I don't know if any stereo setups can work with a gtx card.  That is more likely to work on Windows.
