nVidia Details 55nm GeForce 9800 GTX+

I wonder if the 'old' 9800 GTXs are compatible with the new 55nm ones in a SLI setup? If not, there certainly will be more than a few extremely miffed Nvidia customers that's for sure.

From the sole review I've seen, it looks like this card uses more power then the old 9800GTX, simply because of its increased clock speeds. Of course, it also looks like this translates to much better performance then the old 9800 GTX. But , I still prefer the one slot solution of the ATI 4850.

The Question? Is, Will this be Faster than GTX 200 Series? or It's Just Going to be Cheaper & Energy Efficient? Damn! Don't Like that! I Need Performance & Power!
