FFXIV does have huge textures so the stress is on the video memory. Most other games are ports from 360 and PS3 these days and those systems do have limited vram and the games reflect that. Perhaps dust out the card *can't hurt* or perform some diagnostic with software on the memory.
OMG I had exactly the same problem with my HD5850. Watercooling removed the problem. With HD5870 no problem either (well maybe 'cause my model is watercooled by default xD).
