With the release of the ATI Radeon HD 5800 series of video cards, I’ve been slowly retiring the 4800 series cards I’ve been using in my test rig for the past 18 months. This changing of the seasons inspired me to build another new main rig that features all AMD hardware, including two video cards in Crossfire. Admittedly neither of the Radeon HD 4890 cards I have are a match in specs. You can mix and match cards if need be, but the vanilla 4890 and the quietly cooled 4890 I have in my possession are too far apart from each other to work suitably in such an arrangement.
