for ava you dont need epic internet, you need a normal CPU, but a MONSTER GPU
you need 1GB gpu, if you want to play with a no-lagg, that is high enough that you can aim nearby real-time (hope you know what i mean - i fail aiming at 50 fps - i need my 180)
Edit: A.V.A is nearby top rated f2p mmofps ever, while cf is only mentioned in 30% of all mmofps rankings
P.S.:
mmofps = massive multiplayer online first person shooter
f2p = free to play, <> p2p = pay to play
