Well, the way that GPU technology is progressing, theya re making it very difficult to sell (SLI or CROSSFIRE) to me. I've been doing some serious rethinking about going with a dual card solution.
Look at the next generation consoles. They are incorporating, "One GPU, One PPU and multiple Processors." To me this is much more attractive the One CPU & 2 GPU's.
I'm more interested in this "Ageia Triangle" theory.
I think the next GEN or gaming PC's will be far better off with, "Dual Core CPUs, (1) GPU & (1) PPU.
003... I also just read another article that supports what you said.
ATI and NVIDIA "could" consider adding a PPU to their cards.
I'm assuming that it would be a card probably the size of those DUAL GPU cards... That could be exceptable to me.
