I would think you are looking for trouble mixing video card manufacturers.
For the price of the 2000D, I would think you gould get a couple of GTX570's.
I run two cards, a GTX570 and a GT210, which I feed only one monitor to look at what I am doing full screen.
Hope this helps
I think I read that hardware acceleration only works when the primary monitor is connected to the nVidia card.
Any comments from Adobe?
No, the nice folks at Adobe didn't address this post publically or privately.
I can say that my system with 2 video cards and 3 monitors have been working well now. The two monitors I am using for the GUI are connected to the 570, which the monitor out is connected to the GT 210
There is a black level shift, but I just want to see in full view what the finished product will look like. I own a Decklink intensity, but it is in storage about 3,000 miles away - don't ask!
Well...here is what happened. I installed the Nvidia GTX570 card in PCI express x16 slot.... and the ATI Radeon HD 3450 card in an empty PCI express 2.0x16 slot... downloaded all the latest drivers, set up 6 monitors the NVidia driving the main & second monitor, the ATI driving the other 4.... results - the blue screen of death every 3-4 minutes, even when the computer was just setting idle. So I have now pulled the ATI card and ordered another GTX570 card. This will limit me to 4 monitors (unless I get the Matrox Dualhead2go unit,... not cheap). Another problem was the Mercury engine defaulted to software only mode, even though the GTX570 card was installed. So... I guess mixing video card manufacturers is not a good idea... but boy, those six 20" monitors sure gave a lot of real estate!!!
