Yeah, I am stuck on 2GB 960. I honestly thought it would be fine with my Linux machine, but for a second time I miscalculated as a number of sceneries where it says 2GB minimum, but in reality it really isn't. I noticed the new Carenado CT210
I think the new generation of cards and processors are on the horizon, hopefully I can upgrade then, especially if the ASIC mining machines reduces the demand for graphic cards to a more realistic level :).
For $30, I may have to give it a shot. At worst I won't be able to fly there much, but it just means I will see it better once I am upgraded.
