As we have reported before, on March 11, AMD will launch its Radeon HD 5870 Eyefinity6 edition with 2GB of GDDR5. This extra memory is needed to handle the larger framebuffer when you are running in 6 monitor mode. In all other respects, such a clock and memory speeds, the card is exactly a stock 5870. Today, AnandTech has posted more information on the new graphics card.

Since this is still being driven by Cypress, the clock source limitation has not changed. Cypress only has 2 clock sources for DVI-type displays, so the 5870E6 can only drive up to 2 DVI/HDMI displays using passive adapters. Furthermore if you want to drive a 2560 display or a 120Hz 1920 display, you’re going to need active adapters regardless of clock sources. So if you’re thinking of buying this as a 2GB 5870 to drive your 2560 DVI monitor, you’re still going to be shelling out another $100 for an active adapter. Even with the dongles, it’s clear that this card really is meant to be paired with DP/mini-DP monitors for the long-run.

The Dell 3008WFP is a 30 inch monitor with a resolution of 2560 x 1600, and it accepts DisplayPort signal inputs. Thus if I want to drive six of these monitors, then I will need to add in six active adapters, at least as I understand it.
