does amd processor provide a better performance with amd gpu ? is there any advantage of buying gpu of amd?

Solution
No. Unless you have an AMD APU and a AMD GPU supporting Crossfire.
The AMD APU A10-7850k has a GPU which can be paired with the AMD cards R7 240 and R7 250.
You'll get a significant performance boost if you have the 7850k and you add a R7 250 GPU to your system.

However, different APU's are paired with different cards. You'll have to be careful about that before you buy.

If you're asking if buying the same brand of CPU and GPU would have any significant performance boost, then no. You can have an AMD CPU and Nvidia GPU vs both AMD CPU and GPU and you won't notice a difference.

They say it's better to pair AMD with AMD, but that's a load of crap. From what I've seen Intel and AMD combos are better, and intel and nvidia combos are pretty much the best. I however have a full AMD system as I hate both Intel and nVidia.
