In every segment, NV offers the best value for money. That is price : performance ratio. Multi-GPU setups constitute to a minority, be it SLI or CFX. Most mainstream buyers would spend on a single good card than two ok cards. 2x cards doesn't imply double performance, be it SLI or CFX, again. If I have an Intel chipset, I'd much rather pick up a sweet deal from NV, the 8800 GT or G92-8800 GTS. Unlike Intel, which believes that as long as it rules the roost it could ask whatever price it wants (like $1300 for a YF), NV took a different approach after G92. Both its G92 based products are like delicious pieces of candy you can't just put down being a kid. *slurp*. If ATi resorts to aggressive pricing, NV can do it even better. NV is like the Australian cricket team, they don't grow their asses even if they're in a winning position, they sweat it till the end.
Coming back to Intel and AMD, unless AMD takes advantage of this period and develops aspirational value with the buyer (an art which NV is beginning to master), it's going to be AMDoomed.
