Hello,
I was thinking of maybe buying a new GTX 950 or GTX 960.
However there are some problems to deal with: 2 GB may not be enough for the near future.
Then this could create two new problems:
The GTX 950 seems to miss some shaders/processing units, so it might have a strange bottleneck like the GTX 970.
I also just saw another posting of somebody that the GTX 960 with 4 GB ram would have the same problem as the GTX 970, segmented ram at 3.5 GB.
I would be interested in seeing some benchmark performance test/charts with my testing tool here:

The newest version should be best for this purpose, currently version 0.16.
It would also be interesting to know if the test program worked or failed for some reason.
Bye,
Skybuck.
