Preferable budget gaming GPU

[Weizmann]

Which GPU would be good for gaming and budget friendly between ATI(AMD)or Nvidia?According to my findings popular games such as Assassins Creed,and the Witcher 3 are paired with special Nvidia features such as Nvidia Hairworks and PhysX but Nvidia GPU's are costly,whereas Raedeon GPU's offer remarkable performance at a budget price however games like the Witcher 3 are not paired with these Radeon features and my research also states that Raedeon GPU's are louder.

The GTX 960 will be a good upgrade.

My budget respectively would be:R3000 here in South Africa but according to the US currency I'd be looking at 200$

Then a GTX 960 will be perfect in that budget!
