What are your goals here? I can tell you a 200$ isn't going to run either of those titles maxed out @ ultra settings for a constant 60 fps. You will definitely get dips below that alot, especially with that CPU. This is, of course, assuming that you want to run at 1080p ultra maxed out.
I think you need to adjust your expectations or up your budget. Personally I think maxing games is pretty stupid since a lot of those settings do basically......nothing in terms of image quality. You can lower a few things without any IQ sacrifice while performance goes up dramatically. But I just don't know what your expectation here is. If you're expecting a constant 60 fps in those named games @ ultra settings, well, good luck. I'd say up the budget to 250$ or so for a GTX 760 or maybe even more. Or perhaps bite the bullet and upgrade the entire system. Your target is a bit low in terms of price for what you're asking.
So the questions become, are you expecting a fluid 60 fps? Are you okay with dips? Are you okay with lowering IQ settings? If you're not okay with lowering IQ settings (which I truly would not understand if so) then you need to...again....adjust expectations or up the budget and get whatever card you can in that price range.
