hey there ive just been playing abit of the beta for bf3 and its great im really suprised my good old ati 580 is playing it on full with 1680x1050, just it can lag at somepoints and seeing though as the beta hasnt got the full amount of graphics as the final will is it worth going crossfire as another 5850 would only cost me around 70pounds, but ive been looking on some websites and the nvidia cards seem to out perform ati in nearly everyway.
