Frequent ping spikes even after upgraded router and modem?

[TheGr8N8]

The internet is usually fine when just browsing websites but when I load FPS games the ping frequently spikes even after I bought a new router and integrated modem. I'm guessing this would be either my adapter's issue or the ISP's issue (on the bill I think my parents are paying for 8.0M Internet), should I call Centurylink and see if they have any better packages?

You probably should research if your adapter is any good first. Which one do you have?
