Nvidlovr :
will i miss out too much on nvidia only features like physx txaa gsync if i go with amd?
Gsync only works on monitors designed with hardware to support it, so if you plan to buy a gsync monitor, then yes. AMD has Freesync that is supposed to do the same thing and work without special hardware. Physx is used only in a few games, so if you play a game that offers it and you want to use it, then yes. TXAA...there are so many types of AA out now, I lost track. Both offer some level of AA, so if you want that specific type, then nVidia is it.
When it comes to features like these it's personal preference as to what you plan to use and not use. AMD has a few exclusives on their side as well, Freesync, Mantle, Trueaudio, etc. You have to decide if you will actually even use those features and if they are worth getting one over the other.
