I have an ATI Radeon HD 4250 (PCI\VEN_1002) in a dedicated Digital Audio Workstation (DAW), which is in a desktop PC case. It has DVI, HDMI, and VGA I/O's, but I want to upgrade to a card that has at least two HDMI I/O's to run my LG Ultrawide monitors. I would like to be able to remove the old card and drop in the new card without a lot of trouble. Which cards should I consider? Also, how much trouble is it to replace the graphics card in a desktop PC?
