The first: The Octane recognize and use all Cudas of video cards installed on your computer? The second is: If I use only a basic plate for the monitor and powerful two plates only for Octane, performance is much higher?

provided that Octane recognizes all your cards, yes, the cores will add up and you get more rendering speed. You can also set which cards Octane will use. So in effect, you can free up the least capable card and use it for other purposes besides rendering.
