bottleneck performance?

[einzele]

@Imoye yep thats what i thought, and its true. i thought 20fps at mor dhona is normal, until i compare it with my friend. well, they could lie about it, but why would they do that tho.
@Acyd im not very sure abt my friend's but mine is clocked at its stock speed. does the speed affect much?
@Judge_Xero i thought power option only affect display sleep and such? but mine is already at high performance setting when i check it.
@MaikoRain thanks for posting your screenshot. we both and Itseotle with 980 have similar issue, i guess this is only an issue for 900 series. i did a bit research and there are also many people have this issue with 900 series, low gpu utilization and low fps compared with other gpu models with the same cpu.

a question, if i change the cpu with i7 4790k will i get better framerate? the i5 4460 is clocked at 3.2 - 3.4GHz, i7 4790 is 4.0 - 4.4Ghz. i suspect this game does not utilize hyperthreading, but will more clock speed affect performance in any way?
i bought this i5 4460 because everyone on the web say its more than enough for gaming and u wont get any noticeable improvement anymore than that.
