I've still got the stock GT120 graphics card in my MacPro4,1. Especially after Yosemite updating, I'm seeing degraded graphics performance. So, thinking it's time for a new card. I don't do very much that is complex or graphics-intensive, so I don't need overkill. Just a lot of normal productivity apps, development work (Eclipse and xCode), and streaming media consumption. I currently run dual monitors, both off the GT120, at 1920x1080 each. Would prefer to connect to both displays using the new card using HDMI if possible. Thoughts?
