I tested GTA:V again at 1440p with the FX-6300 OC'ed to 42. Really surprised with the results.
Once again, I averaged the 5 passes.
Min - 29 (-2 fps)
Max - 87 (+12 fps)
AVG - 56 (+11 fps)
Really surprised to see such a massive average fps gain.
Gsync really seems to shine in this setup where the GPU is very much a limitation. Better then it paired with my 980 ti anyway.
