Hi all, currently upgrading my GPU. Have been offered a sapphire 480 and a red devil 580 for £110 and £130 respectively. The reason I'm considering the 480 is due to the amazing reviews of the Sapphire cards, and am hesitant of the powercolor as I have seen some mixed reviews. As I'm buying second hand, I feel safer with the sapphire. They also match very similarly on passmark etc. so I'm undecided. This is upgrading from a gtx 960 2gb.
