How is that a bad thing again?
You post a screen in which it show how dual core CPU get 48 and 43 FPS when stronger CPU get from 76 to 98 FPS using the exact same GPU.?
Did you even see what you were posting.? You just confirmed that yeah even using a R290X which is a $500 minimum GPU with a dual core CPU will kill your performance like there is no tomorrow,and that is with a R9 290X,imaging pairing a R265 with a dual core how much crappy that performance would be.
Basically you just confirmed that dual core are a bottle neck and that 47% is bottleneck by CPU.
i3-3220 sits at 95 fps and is a dual core
