what FPS SHOULD i be getting?

[jinzo]

hi thumper here are my system specs and average fps
my game is on maximum settings
i have
i7 2600k @4.80ghz
8gb 1600 mhz ram
gtx570
a 2 tb hard drive
all on as asrock gen3 mobo
resolution= 1680x1050

my frames usually sit around 50
but when things get a little busy and im low to the deck they may drop as low as 24 ( the lowest ive seen on my rig ) but it doesnt sit there for long

hope this helps mate
