I have a socket 1156 mobo and i5 760 OCed @4.2, you could lower in-game graphics settings and you would need to create a custom configuration from 'game.cfg', also i'd say 4GB RAM at minimum(especially with an older GPU), but yeah, should be ok if you get some more RAM but don't worry if you can't cause it'll still run(i believe).
I do believe your GPU will be fine but i've not much knowledge on those cards.
