This isn't going to be a platform that sells well and Intel knows this. It will however, be THE definition of ultra high performance.
See, I'm actually not so sure about this. I actually think it'll be the definition of an idiotic purchase, at least at this point in time.
Intel believes high-end gamers will be in a state of euphoria...
I don't care how many cores you jam into your system - once the two 8800s (or whatever) are the bottleneck, you're throwing your money away. Is Crysis octal-threaded? Put an E6850 into that setup and the gaming benchmarks probably won't change to any sort of appreciable degree, much less $2,000 worth.
In principle yes, a setup like this is like a freaking super-computer, and I'm sure it'd make a great workstation for a business (if the price ever drops), but how many computer enthusiasts (or 'high end gamers') spend their entire day rendering video?
Lately, everything is Ultra-this, Extreme-that and Fatal1ty XXX Edition. 'High-end gamers will be in a state of euphoria' is synonymous with 'Stupid people will overpay for tech that there is no use for yet'.
