1060, but throw in that extra twenty or thirty bucks and get the 6GB version. 3GB has no future what so ever if you plan to game in a year or two at anything higher than med/low-med at 1080p...
1060 i love my 280x's but they have had problems off and on with the software where some games would freez before start up . that has since been corrected but still stains the ba k of my mind so to speak
