hi, so im planning to upgrade my GTX 950 to a rx 480, my question is do i need to un-install my nividea programs/drivers (including geforce experience) before replacing the card? then just go back on and install radeon crimson and my AMD drivers?. thanks PS; my system after the upgrade will be, i5 6600k, RX 480 8gb v ram, 8gb ddr3 RAM (planning to upgrade to 16gb in the future) will i experience any bottle necking, and over all is this a good system? thanks again
