Low FPS when gaming. R7 200 Series

This computer is only a year old, and I got it because of the high specs. that I thought it had for the price.  However I didn't fully realize until I did a Benchmark for a game it was saying  I was lacking.  I then checked the FPS on my Final Fantasy 14 game and on High settings says I have between 8-11 FPS. So I changed settings to low and still it only gave me about 22-28 fps.  A friend told me I have higher specs than them and yet on the same settings I have they get between 60-120 fps.  I don't know if I need a new graphics card or what ranking mine even is since I never used a graphics card before since used mostly laptops, nor do I know if there is another issue giving me bad or lacking performance.   I currently have AMD Radeon R7 200 Series, and have the current graphics driver update being Radeon Software Crimson Edition (17.5.1) yet no change in fps and the game benchmark saying I'm under the Min. requirements even though I should be fine.   Please Help!!
