A few people close to Intel have shared the opinion that Nvidia became to arrogant and that it need to learn how to behave.
Intel suffers a lot from lack of X38 SLI support but Nvidia will simply not let them have it. Intel needs that to see its X38 chipsets better but at the same time if Nvidia does this it would mean that it would be a death sentence for the upcoming Nforce 780a chipset.
Even AMD will start public war against Nvidia in 2008 as Nvidia is now seen as the competition and you always want to put the competition in place.
It wont be fun to be Nvidia in 2008.
