All I need is:

- Crossfired 7970 Performance (doesnt have to be a perfect 200% scale either as Xfire isnt a perfect 100/100.)

-At least 3 DisplayPorts for my monitors, and 1 HDMI for Rift.
(Tho Id prolly keep my monitors on the system I have now for 3d graphics work etc.)

Everything else is a perk.
-150% More VRAM (3GB vs 8 GB)
-Lower Power Consumption
-Lower Heat Output
-Higher GPU Clocks
-GDDR5X / Higher Memory Clocks
-Same Performance Level with 140-170w Card vs 2x 250+w Cards
-The new GCN1.1+ Feature Set (xDMA for Xfire etc).


Also there was a 3DMark Entry, that has been deleted, showed the same AMD generic Adapter at 1750MHz GPU, and 2560MHz Memory (10.24GHz)..
