At low-medium settings,depending on the resoultionMonsieurX

Will it be smooth on those settings?

Well, Please dont Patronize me if its a stupid question, but can i over-clock it?

You wouldn't get much of an improvement trying to overclock the graphics card, but you might get more life out of that CPU. Overclocking isn't something that should be attempted lightly though, and you'll want better cooling.
