I have AMD radeon hd 7660D graphics card, which what I understood is a decent graphics card that I should be able to play nearly all games with medium settings. Some games runs without problems at all for example League of legends and CS:go, but then again some games like Rust and Playerunkowns Battlegrounds, I have all graphic settings on very low and it's still unplayable with very low FPS. My computer is quite old, maybe 3 or 4 years, will it help if I just upgrade my graphics card? And in case yes, could you suggest any good graphics cards since I don't really know much about this? I Unfortunately Im no expert about computers so I dont really know what specs I got, I just know my computer is called ''THOR Gaming PC'' and atleast it has i5 processor and stuff like that.
