I'm running an Optiplex 780 with 16gb of ram, a core 2 quad e8400 3 GHz and a GT 1030. I noticed that my gpu is majorly bottlenecking my gpu and I was wondering weather a quad core such as the q6600 2.4 GHz will keep up with my gpu or will the .6 GHz speed decrease also end up bottlenecking my gpu as well? If so, which core 2 quad would be suitable for my gpu?
