I really don't need a more powerful graphics card at this point. I don't game on this computer (got a PS3 for that) and very little software can take advantage of it. I assume by the time that software can take full advantage of a high-end GPU, something much better will be available with dual MDP ports and I can get rid of both my GT120's at that time.
For now, the GT120 is the most practical way to add a second MDP port. 😱
BTW, I curse Apple for not fully embracing MDP and offering a card with dual MDP ports... why couldn't they offer a variant of the GT120 with dual DVI and another with dual MDP so people don't have to buy 2 freakin cards if they want to run dual monitors! 😡
