GeForce 840M - anyone achived playable FPS rate?


Hey mates.
I m currently using laptop: i5 4210U (2.5ghz), 8GB DDR3 1600, GF 840M (2gb but just 64 bus).
While I belive that cpu+ram are enough for multiplayer, I m worried for GPU. Does anyone of u mates play evolve on this GPU (or similar) even on 720p lowest settings with playble framerate?
I m asking, cause I wont drop $$$ if I cant plat that awsome game. Tried to look in web for the anserw, but not much related. However ppl runs similar req games with success.
