I would go with the FX 6 core and the GTX 960 as the GPU is more expensive and the FX chips are only getting less expensive.
You'll find that that are games coming out now that recommend the 8 cores:

But going there only takes $130, less after after unloading the 6 core, and you'd rather SLI a 960 someday to squeeze more life out of it (especially with 4Gb vRAM)....
