I suspect you're right about price fixing. However, the fact that someone in the economy has to pay a large sum of real money is irrelevant in determining cost-benefit.
Yes, it's real money. But so are labor costs. And, in theory, those labor costs represent [a portion of] the real value that person is adding to the economy. So anything that makes the employee able to add value more efficiently is overall good.
In general, an employee would not be earning $200/hr on a $7,000 workstation if they weren't adding more than $200/hr of value to the economy in some way. So making them more efficient either allows them to add more value, or gives them more free time to do other things (which tend to benefit the economy and society as a whole).
So maybe there is collusion, price gouging, artificial shortages, or something going on... but I know people who would gladly pay a huge premium for minor speed increases. And that really drives development, which should ultimately benefit the home user.
