CaptainWoopy what CPU and PSU do you have and what budget do you have available as we can all throw graphic cards at you but if either of these components are not up to it then it is a waste of time. If you have a weak CPU then no matter what you put in your computer it will be bottlenecked and you won't get the 45+ fps in Battlefield you crave. If your PSU isn't very powerful or a cheap generic brand or not enough amps on 12v rail it makes this discussion irrelevant. You have mentioned that certain cards are too expensive yet mentioned a 680 in you opening post so how much do you have / want to spend.
Lets take a step back and get the whole picture and then offer advice rather turning the thread into a list of links to benchmarks that ultimately may be irrelevant.
So , I need also to change my CPU ?
My CPU will do bottleneck with the card ? ;\
I have only 1000$ ~ to spend , cant go higer then 1050 $ ..
and I said what are my specs at the topic
Anyways , right now I have AMD PHENOM 840 IIX4 , Gigabyte 880GM UD2H , 500W PSU and 4GB 1333 MHZ .
But , I want to buy with my vew video card also 750W TX CORSAIR PSU , 8GB 1600MHZ CORSAIR VENGACE , and maybe 180GB SSD of Corsair 180gb
