how to change graphics card in macbook pro 2012

I thought it was an external graphic card, I had no idea that the processor would be doing the job instead (and very poorly).įurthermore 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). 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 have tried DisplayLink USB to DVI adapter but it's really choppy and unusable for me (photo and video editing). What I am trying to do is have dual external screen (Macbook Pro docked and closed). Or else is it possible to add another graphic card in (or outside) the Macbook so that I can use another display.

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?
