I have early 2009 (Nahelem?) Mac 2x2.26 quad core xeon
NVIDIA GeForce GT 120 512 MB

Since I am not sold on the cylinder Mac, I'd like to enhance this set up.
Would bumping up the graphics card be the best bang for the buck right now?
I use everything adobe. Are there known preferred cards? I'd also like TWO DVI slots on a card instead of one DVI + analogue slot.

Any advice, thank you.
