2gb cards are now on the REVISED BY AMD design, and it's not just XFX. Add Sapphire, Powercolor, Visiontek, etc etc.
There is the original reference design, and then there is a second revision by AMD which some companies use (PowerColor 6950 2GB PCS for example) and then there is a non-reference design they also use (Powercolor 6950 1GB for example; Sapphire also have this).
The second revision cards have a much "cleaner" looking layout on the rear and have white outlines around the GPU area (mounting brackets) as well as all around the PCB - where as the other version does not. It was very similar to the reference cards that had the backplates, but the manufacturers used their own components etc.
The "rev2" pcb cards are kind of dying out too. They all had the bios switch, some of the new ones don't.
Here is what the original "non-ref" PCBs looked like and the new one - Not the exact same model but you get the point.
And the new ones:
