I have seen this type of argument many times and it baffles me how many uses it.
Its like buy a 10% more expensive car and you can acellerate 20% faster.
Its completely ignoring every other component in the computer system or car.
With that logic everyone should buy 3 times as expensive computers.
I know its a personal preference but applied to eg. Cpu or gpu the result of the bad logic is just crazy expensive stuff.
And the real world is just not that simple. You have a more or less tight budget. The answer is then how do i get best playing experience here?
Obvious you just cant double the price of every component just because its a benefit. Its about cost-benefit balance.
Are you trying to say that no one has a right to buy more than the cheapest car, house, computer, TV, cell phone, whatever that will do the job? Maybe no one should be allowed to have a smartphone, a simple prepaid cellphone should be good enough, right, or maybe just find a phone booth.
I did not say anyone has to buy a 3570k, they can buy an athlon x4 750 for all I care. And yes, there is a limit to what is reasonable to spend. I would not recommend an exterme edition cpu, because the cost is outrageous compared to the increased performance. The point I was making is that is not the case for a 3570k. The increased performance relative to total system cost is actually greater than the relative increased cost.
But if someone has the resources to buy something above the bare minimum, who are you to say they dont have the right to do that. You are extending my comment to ridiculous extremes far beyond what I intended, and I think that is obvious. If one carried your arguments to the same extreme, he could say nobody should spend the money for pc gaming at all, they should go to the library and check out books for free.
