"Enthusiast" is often a word that can be stretched to suit a particular user, or in a way I would consider myself a enthusiast, but not a performance junky. The performance junky buys the 2700K or 3960X under the belief it will create a better performance matrix than the other chips, a fact which is rebutted and disproved. To me I am a enthusiast but I don't feel the compulsive urge to buy something that is far more expensive for a marginal gain.
We also need to consider the different approaches from AMD and Intel, to me AMD are far more consumer conscious and design to give the end user more goodies for less (exclude performance debates), and thats what you tend to feel when you buy a AMD setup, not really that expensive even for a high end hex or octocore on a highend platform along with all the bells and whistles. Intel for me chase the dollar sign, they target a specific user, namely the enthusiasts(overclockers and hardcore gamers) or hefty server market, they have neglected the basic consumer market and populated it with overpriced "lowend chips" with very little joy for the basic end user.
The indictment of the claim that Intel dominate the budget spectrum is when you are tasked with taking $300 and seeing what you get. The AMD APU's for a person looking to game on the affordability bracket can get a APU which on IGP performance obliterates anything Intel has on HD side, with the option of asymetrical crossfire which is a factor which makes it very appealing for a person that wants to play at medium settings on high res and higher settings on older conventional res.
The other factor which is overlooked is the money, intel is a global corporate monolith with resources that petty AMD's resources, more money results in better products which is true in this case but a question is; do you honestly believe you get all you can get from intel. Every Intel chip I own feels watered down and bare minimum. Some say Intel doesnt need to or is not obliged to give you more due to lack of competition. I reject that arguement on the premise that every corporation is obliged to give consumers the best available product irrespective of the competitions standard, by holding back and overpricing it is bad business practise, but why would they complain when people are happy to be overcharged for a little slice of psuedo paradise.
