odds are the driver will function with either, although I highly doubt the 4 card setup will catch on. I'm pretty sure that's the direction we'll see cards go, two chips per card.
I Think It`s 2 Card With 4 Chip , Like ASUS Extreme N7800GT Dual ( 2x7800GT Chip)
and 2 of this Card can run FEAR in 92 FPS ( While 2x7800GTX runs 50 FPS :twisted: )
Ohhhhhhh , Too Expensive For Me ...
