After a point, XIV appears to be more limited by your CPU than your GPU, as is the case with most MMOs. Obviously there's a lot of debate among people about what to use, but my system (which runs very close to Ultra; I turn the shadows down a bit) is a Core i7-930 with a GeForce GTX 770 and 12Gb of RAM.
If all you do with the computer is play one MMO, you'll find that the build plan is simple. Get the beefiest GPU and Intel CPU you can find in your price range and at least 6Gb of RAM; CPU clock speed is more important than number of cores, since MMOs, like most games, largely aren't heavily multi-threaded and so don't scale across additional cores especially well. (That's why I recommend Intel over AMD; AMD has an advantage in core count per dollar, but that won't help you so much with games.) Also, the XIV client is 32-bit, so it'll never use more than 4Gb of RAM. If you can afford it, SSDs will dramatically improve your load time and improve your performance somewhat in character-heavy areas like cities (as they improve texture load time). I use Crucial MX100s, which are quite favorably priced.
