I looked at other questions like this, and a lot of people say it depends on your build, what games, and how much watts on the psu. Are those true?
Not really. Any PSU over 500W is plenty of any of those cards. The performance difference assumes that the exact same game is used to benchmark all the cards at once. In other words, a different benchmark might yield different results, but this is a general benchmark for the majority of games. As for the build, as long as you have a semi fast CPU, there's no worry about a bottleneck.
