What is the difference? GTX 970 GPU

[Zusagid]

Couple days ago bought the EVGA GTX 970 SSClk 2.0+, but my question is: what is the difference between all the ones that are on amazon's list there? is it just different Overclocking speeds? Or something different?

You've pretty much answered yourself already. Yes there are some reference models and others factory overclocked models. The real difference in game is a few fps at most.

There is also difference in versions 1000-KR, 2000-KR, 3000-KR etc, the higher the number the newer version it is with improved cooling system.
SSClk ACX 2.0+ you bought is 3975-KR so it's latest version for GTX 970 and good card.

Not much difference, but more expensive cards are usually slightly stronger withn the same price range.

Also , basically each brand has it's own cooling gimmick. Some come with additional features like perhaps a backplate.
