I'm thinking to upgrade from a HD7770 to a GTX 960 and i want to know if my FX-4130 would bottleneck if i did so. Plus i seem to be getting constant lag spikes in cs go with my current setup, i have 1x8gb 1600mhz ram so i dont think that could be the problem, well i think it is enough. My settings in cs go are pretty much the lowest...
