i play this in 3d nvidia on my 120 hz lcd
its sexier than this!
it seems more real life due to the 3d effects and characters 
and it costs more than your 3 samsung 19" 
but ti shows you have 5 monitors?
why not just sell them all and buy a 32 inch hdtv or some sort instead lol.
also i don't think your playing MAX out settings such as
every very high with 16X AA are you?
because i think you need a higher card than a GTX 260.
im playing on a GTX 295 and its perfect for this game but i do notice tons of fps drop due to the 3d
