I can't understand why the fps is so low on 780 sli benchmarks at 2560x1440, I've only played it at 7680x1440 this morning on ultra no AA but it was a steady 45-55fps and hitting 70 in jets etc so I'm sure at 2560 it will be much better, anyway I will need to try it tonight and see, I was going to change for 780's but doesn't look like I will need to now. Also I'm hitting 3200mb Vram so the 680's only replacement can be Titan but not paying that money
this game will run so smooth even at 30fps when I run Fraps record its nothing like the beta was, I'm sure 290x crossfire would feel crap at my res like all other Amd cards I've had before but time will tell (fingers crossed) :s
