Yeh but you aren't providing all the information, you are pretending that everyone will get the benefit from spending large amounts to for high refresh and high fps when lots of people wont so you should at least caveat it.
I am not pretending. How can you possibly claim to know anything about me and how I am saying things? Ad hominem attack after ad hominem attack, its not doing anything for your point of view. How could I possible provide
ALL the information regarding anything? I could make that same argument that if you do not provide all the information you are the one with an invalid point. We give opinions not masters thesis's on every potential. There is a clear statistical and real world benefit to having more powerful graphics cards especially when the performance is so closely in line with price for most cards I have suggested. You seem to think that every game is going to run at 300 fps when in reality not all will. A year or two from now when more demanding games come out their performance will suffer more than necessary at the same settings if buying a graphics cards that just meets the needs of now when you have in your budget more money available to you. You can buy the minimum best graphics card that will get you the minimum 120 fps you want every 2 years if you want. You will find that is a more expensive proposition. I personally buy a graphics card once every 4-8 years, so it mind as well be the one that is close to the top of the stack without too much diminishing returns.
The decision of where the diminishing returns are is in the eye of the beholder. As such we on this forums give our opinion of what a user needs given the circumstances of their build such as, what monitor they have or are going to use, the games they are going to play, what their target framerate is, how long they intend on getting those frame rates for, the budget they have to work with, and what country they are located in. You can disagree with my opinions all you want, but as soon as you claim that, "its scientifically impossible to see X framerate," and make baseless ad hominem attacks as a detractor to our opinions, you are going to get into arguments with people that generally know what they are talking about more than you.
