I have the same video card and run FFXIV on my smaller 1280x1024 monitor at standard foreground and background distance, but with lower shadows and texture filtering. I can run it in 1080p as well, but with choppier framerate. What may limit your experience isn't the video card here, but the CPU. This game is very CPU intensive, keeping it running warm almost constantly, and I have a quad-core 3.2 Ghz Phenom II.
