How good can my Lenovo S410P perform? (4th gen i7, 4gb ddr3 ram, Nvidia GT420M)?

I'm considering to buy the Lenovo S410P but I'm a gamer and I wonder can I play games on the laptop with these specs? I'm not that picky at graphics but I want to at least know how far can it go. Can any computer expert just briefly explain to me what should I expect out of my machine? Can it run bf3 or crysis normally? (not necessarily ultra settings) Please and thank you.

It seems like a great computer, but since it is a little low on ram you will have to most likely close out of all other programs before running a big game like boyfriend or crysis, but it will run these on med-low (most likely low) settings. Hope i helped!
