Okay, so I have this graphics card running in my computer right now, and I can say that it runs Blockland very well, even with soft shaders/shaders. Most of the time, you'll be getting 100 FPS or above. Other games like CS:GO and BeamNG Drive will run fine, but BeamNG will run a bit slower at an average of about 20-30. It's still playable though.
If you have any more specific questions, feel free to ask.
