It's still for sale and I offered the guy $400. What card would you buy if it were you? I'm not a big MMO player or anything, but I like the idea of being able to if I decided to. Things like Skyrim and such are my bag.
MMOs tend to be less intensive on the GPU than other titles. Right now the only sane option for buying a GPU is going nvidia. All the AMD cards are stupidly overpriced due to demand. Depends on your budget, but the the X60 models on nvidia are the upper-midrange cards and the X70 models are the high end. X80 is the very high end stuff. So right now the 760 is ~$250 and the 770 is ~$330.
