building a pc for this game

[Dsync]

GPU is the most important part for FFXIV so you need to buy a great one.

I found a decent cpu to be the most important. A 770 in my old machine(amd 3.2 black oc@3.6) gave decent framerates, but when I hit busy areas it would tank to 30-40. Put the 770 in with a better cpu and I now have over 60fps, even in busy situations. It's my understanding that mmo games by their nature are more cpu intensive.
