which gtx 980?

[Nik Golob]

I can only get one of these one:
-Evga gtx 980 sc acx 2.0
-Gigabyte gtx 980 windforce oc(is there any difference with g1?can it be oc-ed to the level of g1?)
-Gainward gtx 980 phantom
-zotac gtx 980 amp! Edition

Which one should I buy?

 

[gokitty199]

as far as i know the gigabyte windforce is a little slower and has no backplate compared to the g1. out of those i would choose the g1 if possible, or just the windforce
