Want to upgrade my computer for this game, need some advice.

This is actually not true. A lot of websites, reviewers and actual tests have shown that the 380 and 390 completely desrtoy the 900 series if it's within the 200-400 range. Once you go over the 400, amd is too expensive for the price per dollar, so the 980 TI and titans win there. I don't know about the 370 or 750 though.

250 or less range. 250-400 is not what I consider budget unfortunately :3

Unfortunately, no. It isn't one size fits all. You'll need to determine what your case can handle, then pick a card based on that. And generally speaking, yes. But in this case, the 950 actually draws less power. It's also smaller. So if that's what you settle on, you'll be set.

What to do is build your PC on this site: http://pcpartpicker.com/

It lets you put together every piece you'd want, finds the best outlets to buy those parts in your Country and warns you if there's an issues about compatibility.

Oh that's just a great link, thank you!
