Thank you all for the fast responses!
Someone of you asked which I prefer, I prefer Nvidia.
And I'm trying to play all the new games such as The Witcher 3, GTA .. etc etc
Also, I'm little confused now, can I overclock my cpu now or not? Because some said I can't since its not ####K Model and some said I can, how can I know? Which parts should I also have in order to overclock it with ease.
Oh and also, what kind of Power Supply I suppose to have to make everything run smoothly?
Thanks again!
