So if i want higher FPS i should buy a better grapich card ?

I have an Intel Core i7-4770 CPU @ 3.40Hz, 8GB RAM, NVIDIA GeForce GTX 750 TI and I get 80 fps in empty places but it drops to 30-40 fps when I'm fighting a boss or when I'm at a WvW.I've already overclocked a little and got the last update to my NVIDIA using NVIDIA Experience.Am I suppose to get this kind of graphic lag ( because of my system requirements aren't enough to run GW2) or maybe there's something wrong with my computer? I'm running all my settings inside the game on low.Thanks for the help.
