None of those games should be a particular problem for a modern discrete GPU.
How much are you willing to spend on your GPU?
Even something like a Radeon 7750 should run those games.
I would want something far more than a 7750.
I will probably be playing more intensive games than just this and I can play around with the budget, so I would probably pay like $350 or so. I also don't know much about GPU measurements, but I was opting for a 7900 series Radeon card. Money is not that big of an issue but my entire rig budget is $1500. (And I don't know much about how much the card's price would be in relation to the entire rig.)
