nVidia is safe on DMI but not on QPI.If intel won't allow nvidia to provide their motherboards and gpus and instead saddle us as in these quads with their stone age gpus that will make their cheaps hotter, then apple is in for a messy situation considering their close ties with both intel and nvidia. And pretty soon AMD at their prices and ATI's gpus being IMMENSLY better architecture than intel is the winning combo to anyone with half a brain outside the pocketed by intel online pundits. Now with snow leopard using the gpu more effectively too, it's even more so. Who will get a $1000 intel quad with crap intel graphics instead of an amd quad with ati which will be maybe 5-10% cpuwise worse off than intel but HALF the price and with a 10 times better graphics solution from ati, or for that matter nvidia. It's a no brainer.
Like I said before I'd like to see what chipsets go along with these. There isn't an IGP solution right now until Intel ships it onboard with the CPU.
