Is that possible to replace the existing graphic card of a Macbook Pro (Mid 2010, Mini DisplayPort, GPU: NVIDIA GeForce GT 330M) for a graphic card that could support 2 screen output?
Or else is it possible to add another graphic card in (or outside) the Macbook so that I can use another display.
What I am trying to do is have dual external screen (Macbook Pro docked and closed).
I have tried DisplayLink USB to DVI adapter but it's really choppy and unusable for me (photo and video editing). I can't even watch a video on it, you can even see the difference when moving the mouse (and I have a i7 quadcore processor -_-). I thought it was an external graphic card, I had no idea that the processor would be doing the job instead (and very poorly).
Furthermore I don't want to spend $200 or $300 to try the Matrox DualHead2Go and finally consider that the fact that it's one big "screen" extended over 2 screens (and not 2 real screen separed) is annoying (i'm really afraid this is would be a pain).
So I'm looking for a real solution for Macbook Pro dual external screen.
Change my graphic card? (I don't even know where the second video output would go...). Or add another graphic card externally? (USB? does that even exist?)
