Anandtech has a nine page review of the AMD Radeon HD 5870 Eyefinity6 posted. This card sports 6 mini-DisplayPorts, and comes with two mini-DisplayPorts to DisplayPorts adapters. In addition, it has 2 passive mini-DisplayPorts to single-link DVI adapters and one passive mini-DisplayPorts to HDMI adapter. The GPU core runs at 850MHz core and the memory runs at a 1.2GHz clock, just like the regular Radeon HD 5870. Other than the 6 mini-DisplayPorts, the only difference then is that it has 2 GB of memory. What does Anandtech think of the new card?

As a general gaming card however, there are definite issues. In existing titles, with 3 or fewer screens, we just didn’t see a tremendous performance advantage to the 5870 E6. The larger frame buffer did help raise minimum frame rates, but not enough to positively impact the average frame rates in our tests. Even in triple display setups we didn’t see any reason to get the E6 card.
