If Lucid's Hydra 100 actually will work the way they say it works then its going to change a lot.
You will be able to buy 2 low-mid range card and improve performance X2. That would be insane
I wonder what this would mean for high end GPU's, they'll have to make unique features other than performance benefit to draw the crowd...
I have doubt it works "as advertised" though.
On topic: great scale for i7. Need only to drop prices on these and i'm sold.
