Choosing Graphics Card

[CookieMonsta]

Thanks for your responses! I am considering between GTX 1060 6GB and rx 480 8GB now. Leaning to invidia. I should have listed the specs of my PC.

A couple of points you have to consider. While the 1060 is a superb card, its borderline impossible to find a good model from a good manufacturer at the price range you want, by all means if you want to splurge extra then its one hell of a card. The 3gb 1060 may be good on paper but it will become a useless paperweight in the future since the 3gb of RAM will limit the card long before the GPU power becomes an issue for modern games, you will be basically paying a lot of money for a powerful card that becomes crippled once games exceed 3gb of ram consumption.
Basically, if you intend to keep the card for 2+ years then the RX 480 8gb is much better balanced for that price, if you want absolute cheap then the 460/470 are the best picks which would provide acceptable performance for FFXIV.

If it makes your decision easier, absolutely nothing will help with Idyllshire lag because thats a CPU issue not GPU. The full reason is complex but even the best CPUs + GPUs will still lag in idyllshire cuz of the sheer number of bodies there.
