Hi, I was wondering. I do have a mac pro 4,1 with 18GB RAM (3x4GB + 3x2GB) and 2x 2,26GHz CPU running on several SSD's for both OS and scratch disk. I'm currently using a 27" screen but resolution doesn't seem very good with the standard card, which made me consider... Still running Mavericks but willing to upgrade. I wish to use the mac pro for audio, photoshop and small video work (after effects+premiere). Everything considered I'm still happy with the machine besides the graphical card. What is the best solution for a graphics card that doesn't break the bank and runs silently (with mini displayport or HDMI output)? What do you guys suggest? Thanks in advance. ps: I'm not that tech savy in mac upgrades in general.
