Heard some people like Gigabyte are working on dual core NV6600 and NV6800 GPU's so my guess is that they may show for mobile systems sometime later on by the second half of 2006 or the first half of 2007.
By seeing the above I guess that we will be seeing an SLI set up sporting four dual core GPU's.
Of course, you will need a huge bank account, monster power supply, monster case, monster cooling, monster memory and a monster processor(s) to be able to handle that. Most probably you will have to go with a dual core CPU or two.
Anyone up to the challenge to make one of these monsters once they come up?
