Different versions of the Gigabyte gtx 1070?

[NotSteve]

So I'm getting a gigabyte gtx 1070, but before I wanna know the difference between the versions. These versions are:

• 
  Gaming G1
  1070IXOC
  1070WF2
  1070WF2OC
  And the 1070Xtreme

If someone could tell me the difference between these versions that would be great, thanks in advance

From best to worst :
Extreme > G1 > Windforce OC > Windforce
The performance is similar between the cards. (1-3 fps) However, the extreme gaming has the best temperature.

So even if I didn't want to overclock then the extreme would still be better?

Yeah but the extreme is the most expensive one.
