Matrox M9140 LP PCIe x16 Quad Head Graphics Card - 512MB GDDR5 Memory, 4K Display Support for Multi-Monitor Workstations | Ideal for CAD, Video Editing & Financial Trading

I have used two of these in two different computers and they have worked well. Recently, though, I had an issue when I upgraded to windows 10. Word to the wise: go to the matrox website and download the windows 10 driver before you install windows 10. Otherwise, have a backup graphic card to utilize because upon updating windows, without updating the graphics card, you will get a black screen and cannot do anything.
