I can't tell whether from your post whether or not you plugged in the additional power cable from the power supply. Most video cards nowadays need more power then can be provided from the slot its plugged into. http://cdn.agilitycms.com/xfx/MediaG...SC0132%201.jpg see the port at the top and rear of the card? That should have a cable from the power supply attached to it. Since you have some extra memory lying around might as well use it, it might not help specifically for FFXIV but it should improve the overall performance for other tasks.

I know the nvidia cards do it, but if you don't have the power plugs properly connected, it gives you a warning when you boot the PC and wont even load to bios. At least in my experience thus far with more modern gcards.
