Performance - dGPU - Gaming with Dedicated Graphics card
Dedicated graphics performance then. with a GeForce GTX 780 Ti. You can check out the differential in-between say a Core i7 4770K/4790K and Core i7 4790 of course.
We test at Ultra quality settings which is a bit unrealistic with today's dedicated cards. The performance benefit in-between the CPUs is nominal to say at the least. That is the reality anno 2015. This is going to be even closer with upcoming DX12 games.
With this GPU and medium image quality settings will never be GPU bound, and this displays CPU and mainboard performance difference really well when something changes in the system.
