Can i play batman arkham knight in my pc?

It doesn't matter if it work slow the game is yet to release but i'm too hyped but i always wonder that will it run my pc or not.
I have lenovo g50 core i3 processor 4gb ram 2gb dedicated graphics will it work?

Yes of course but not play in ultra graphics mode

You don't say what CPU or GPU you have. The i3 line is really low end and is generally below the minimum requirements however. You will also be below the recommend RAM.

I have a lenovo g50-30 can i play batmna arkham knight on it
