My isp tells me the general rule of thumb for fps's online is 1GB = 50 hours of gameplay . Are you from New Zealand ? I'm with telecom , the 3GB plan , about to upgrade to the 10 GB total home package . 3GB ain't enough for me lol .
It also depends on the level your graphics are set on . I get on average about 5 - 7 more hours when my graphics are on all Low quality , as opposed to high quality .
(for the record I only use High Quality now because it looks so much better , stuff the 5-7 hours )
So yeah , get back to me ,
