I did read somewhere (dont ask me where) that the memory bandwidth on the gfxcards in general wasn`t as yet taking advantage of GDDR3 and it`s controller.
What would supprize me is if this gives u any significant performance change for the $14, or whether it behaves like a GDDR3 controller with GDDR4 chips. GDDR3 is going to run it`s course I would imagine.
What I would bet tho, is that the clock speeds would be that much more flexible for increments :yumyum:
