Recently, I've been having some major issues with my Radeon 7870 graphics card and have decided its time to invest in a new card. I am very out of the loop with Nvidia's technology but I don't want that to stop me from buying a good card should an Nvidia one prove better. I had been looking at the difference's between a GTX 770 and the AMD R9 280X but I am by no means settled on any one card in particular just yet.

I really only play FFXIV right now but I want this game to run on MAX, and look great! I would like to stay in the $300 price range if possible, if you could share your experiences with some higher end cards in that range I'd appreciate it!

My current specs are:
Windows 7 64-bit
i5-3570K CPU
8GB DDR3 RAM
Radeon 7870 GPU (on the fritz)
