Thanks a lot for your answer! yes, you’re fully right concerning support. And I also think that so expensive video card will not make whole NLE just a “light process”.
Now I’m planning buy Quadro 4000. It supported by both systems and hope will more relevant purchase for my tasks, as compare with too expensive Quadro FX 5800.
Of course everything is relative, but make experiments with such prices is too big game for me.
If you have any objections against 4000, please post them.
