I'm using Zotac GTX 1060 3gb Mini, only one spot so far i found will hit max gpu load and drop to 56-57 fps, i would said GTX 10603gb/6gb would be sufficient, especially OC version. Budget wise GTX 1060 3gb OC version is sufficient for this game. I found out have noticeable performance gain in 3.0 ff14 after upgrade my 1600 DDR3 to 2400 DDR3 in Goblin City which i hardly see any fps drop while walking/running in this town.
