Not sure what I've done now but whatever.
I assumed that quoting you in my reply was clear enough. Here's an explanation:
You wrote this:
So instead of spending the same amount of money to get more performance you choose to get the same performance but save £100?
Why am i finding that hard to believe, could it be that outside of the money is no object type of people I've never heard of someone deciding on what GPU to buy based exclusively on performance, how most people seem to set a budget rather than a minimum required FPS.
You never heard of someone doing that. Now you have heard of someone doing that. More than one person. There are people who don't set a fixed budget and spend all of it, never spending less regardless of what's available at a price lower than their budget. There are people who set their budget as a maximum spend, not a required spend.
