Only if you wanted to run a multiple card setup.
Since you have stated you don't game much I would suggest researching which card works best for your needs AMD or Nvidia and get one with a large amount of Vram
One problem I see for you is the low amount of Vram your card has for your large monitor
your motherboard does not support SLI so for a multi card solution you will be limited to AMD
Any new gen graphics card would be an improvement...
