have you thought about the fact that these cards consume 200-300W and that to have 5 of them your PSU may need to be monstrous?

Also seems this only makes sense now if you want o resell or use those cards elsewhere .. if buying only for Bitcoins some cheaper cards may make more sense based on how much processing power you get per card cost.

7970 - 600MHash/s and $400
7770 - 200MHash/s and $100

7970 consume 270W and 7950 consume 190W. I am only going to have 4 GPU to start and when i add more down the road i plan to add a second PSU.

You would need way to many 7770 to make it worth while.
