What you say is true. But one of the reasons Dell started shipping their computers with AMD was because of their reputation among the enthusiast. It was the same reason that they ship with Intel. We may make up a small percentage of the market but we have the power to change the perception about a product. It's called aspirational marketing. For example, we all know people aren't going to buy Toyota's super cars. So why make them? Because they increase the sales of the other cars as it shows off Toyota's engineering prowess. Similarly, if Intel loses their position it could have dire consequences on the average consumer.
Some of you may suggest that the majority of Intel's share is in the corporate market. True, but I don't think any company wants to concede the enthusiast share either. This is the market that provides feedback to them.
At the end of the day, Intel's profit gains from the extreme edition processors (which will undoubtedly be fairly small) will be offset by the fact that for less than $300, there is nothing for the average enthusiast overclocker. It will be likely then, that this site will have a few more phenoms
Yeah, quite a few more AMD computers. Quite a few less Intel fans.
