I have an amd phenom ii x6 1100t 3.3 ghz cpu, and a crappy hd 6670, I am planning on upgrading to the hd7850 to play bf4 on max, i'080p and i think thats all ve seen countless youtube videos with bf3 maxed with the hd 7850, averaging at around 42 fps. Is it enough? other specs i have: 12gb ddr3 ram, i'l be playing at 1920 by 1080p ty * i also know that it is not out yet, but just a rough estimate on seeing how it's able to max bf3 do you smart people think the 7850 will be enough?
