Hello, im upgrading my old pc, actually almost everything. Im going with ryzen 5 3600x cpu, asus rog 570xf motherboard but what im realy not sure is to buy or no another asus's rog rx480 oc 8gb so i would be able to make crossfire.. card would cost me just 100€ and i have one already.. should i sell one i have and buy what i can get or would crossfire also be good idea? And yes i plan using it for gaming mostly.
