Radeon 4850 and 4870 Crossfire review. Since Radeon series 4800 cards offer so much value it might even be interesting to pair them in CrossfireX mode. See much like NVIDIA’s SLI offerings AMD’s ATI solution can be paired and matched as well. So pretty much today we’ll place several cards together in CrossfireX mode first the cards paired two and then we’ll for the sake of it see if we can pair three cards CrossfireX mixed meaning 2x 4870 and one 4850.
