 With the CrossFire Xpress 3200, two normal cards can be run in a Crossfire setup, using the PCI Express bus for communications.This is similar to X1300 CrossFire, which also uses PCI Express, except that the Xpress 3200 had been built for low-latency and high-speed communication between graphics cards.While performance was impacted, this move was viewed as an overall improvement in market strategy, because Crossfire Master cards were expensive, in high demand, and largely unavailable at the retail level.
