GTX 950, GTX 960 segmented ram systems ?


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.
