Hi, recently i bought a new gpu (GTX 1080 8gb Founders Edition) and it doesnt work as good as i tought. for example my old gpu GTX 750ti give the same performance that the 1080 gives and i also tried my brother's gpu GTX 1060 6gb and it also give the same performance in my computer.
It runs csgo lowest settings in about 150 fps and i dont think its enough for GTX 1080.
and i tried many games and i have the same problem it just not doing its job.

I hope i gave all information you need to help me solve this problem. Thanks!

Intel Core i7 4770 3.4ghz
Intel DH87RL
8x2 RAM
650W Supply Power
120gb SSD Samsung
GTX 1080 8gb Founders Edition

I actually bought this computer in 2013 and i upgraded my ram ssd gpu and power supply. I tried PUBG, CSGO, Fortnite, Rust, Fifa 18. and i did try to uninstall my gpu drivers and installing the latest. and i even installed my gpu to my brothers and it worked perfectly.
