Problem is that most systems get bogged down at Max Setting due to how other players are Rendered. It maxes out a single CPU core for that process while the GPU is completely under utilized.

A decent upgrade would be an Intel i5/i7 but that would be nearly a complete build especially going with Skylake since it uses DDR4 Ram.

I currently have an i7 and a GTX 980 but I only run Laptop High so I get fluid frames and still have all the eye candy.
