there is always the nvidia bench site or just type battlefield 3 and the name of the card,and then you see^^ i say what i see but it's actually not my pc and my dollars,i think that you are the one who must make the choice,after all i gave you a few results of benchs,now it's up to you^^
at least ,beats a 670
Battlefield 3 GTX 670 Gygabite Réglage Perso & Ultra - YouTube
ill traduce, he says that in ultra the FPS is 65-100 and its a damn OC card from gigabyte!
and i noticed that in your vid,its 80 FPS in a hot action scenee with explosions..jumps to 100 even in fights..
so well,2 GTX 570 would be like 90 FPS in fights,maybe 80 in large maps and a non OC 670 would be more like 70,with what i can see,may depend on the map and the game, btw my bench was for crysis 2,its a really hard game and the SLI seems to work great in it
se yea,you can get a very good 850W psu for 150 dollars i think, and then the card,yea would be expensive but well,you can always buy a 670,but i think its less powerful.. unless you buy a good SOC card or something like that! would be same ,but would be like 500-600 $
and 500 dollars is the price for a PSU + a 570 i think,,its a very difficult choice,if it was me i would not know what to do,take the SLI for perfs or a 670 for simplicity
depends on your case,good cooling? want the max performance per dollar?
SLI is generally recommended for upgrading but when it's not enough powerful you have to buy the next level card,renember,670 is very expensive..
now time to make your choice
