Hi man,
well I guess you could but depending how you want to play it. I mean like others say and I can't disagree with them is if you wish to have high frame rate and avoid drops or freezes, or if you wish to play of average/high settings you will need a better card.
By the way what you are showing us are the recommended settings, which means they show these kind of requirements so you can enjoy the game in it fullest.

As you can see above compared to the minimalist setup you need you are far over what they ask you to have so again come to the same point. If you want our opinion, or in this case mine. Buy it, play the games and try it out yourself every rig is different and if you are not happy with the frame rate or drops just buy a better GPU. You get what you pay for my friend.
Last but not least for the money you pay for it, quality=price ??! I'd buy it.
Kind regards,
Neophytz
