Tips for reaching over 144 FPS?

[Darkobra]

144 versus 60 fps is a HUGE difference in my eyes, mainly because I play competitive FPS games so I tend to notice even tiny flickers and details much faster. It's not for bragging rights, I just want to see if I will need to SLI and purchase another 980 to hit 144 fps.

That's exactly my point. You'll notice fluctuations. Find a STEADY framerate. And one 980 won't take you that high in an MMO. Although DX9 is useless for SLI and you'll need to do it in DX11.
