GPU Hardware porn. Note the triple power connectors.
This may not ever be a released board, but it’s fun to think about. Asus did the same custom craziness with the very limited edition MARS I which had dual 2GB (each!) GTX285 GPUs.
I would place my money on an official dual GF104, though. GTX495? It will fit the 300W power envelope. GTC is in two months. I’ll buy 4.
