greenerization :
Oh. I asked the shop if i could upgrade the gpu and he allows it. So im thinking of what gpu should i upgrade to.
Do you mean you want something better than R9 280x now?
There aren't that many choices, since the 280x is quite respectable. From your dropbox file, I'd say one of these:
Asus GTX 780 Ti
Asus R9 290x or Gigabyte R9 290x or Sapphire R9 290x
Asus R9 290
Asus GTX 780 or eVGA GTX 780
I sorted them with the fastest first. "Fastest" as in fps in Battlefield 4 at 1080p - the order will vary in other games because differences are small. Think 65 fps to 75 fps for all of them (and 54 fps for the 280x).
