Hello guys I'm back! I hope you will see this reply sooner or later. I had installed few games today and those are: Elder scrolls Skyrim, Farcry 4 and GTA IV
All of these games believe it or not run at maximum ultra details with 1920x1080 resolution.
Here are some screenshots of Farcry 4 options >

Playing this game on fullscreen and I also used fraps. It showed that I have around 520-580 fps at every stage of the game. I don't know how much these numbers are actually true but I'm impressed with it. Everything is so smooth and working like a charm. (I couldn't screenshot the gameplay it didn't work for some reason...)
I don't wanna say that you are wrong guys, but I just got different results! Maybe because these are just old games but i'll see what happens when I install some new.
Later on I may upgrade my computer even more but now I'm satisfied.
