From what I hear it will but you may need to turn off some of the weather effects. FFXI is not really a video card intensive application, it depends more on memory (howm uch you have and how fast it is) and CPU speed but more twords the memory then CPU. I would suggest the NVIDIA Ti4200 minimum for FFXI tho as it runs smooth with this card on a system running 512MB of DDR SDRAM and a 2.53 Intel P4 CPU.
