Yeah I understand what you're saying. I'm not going to read through this whole thread, but I can assume your good- intentioned caution about picking a GPU for the beta's "Ultra" settings won't translate to the same FPS with true "Ultra" settings come release has been ridiculed into oblivion by those who don't care much about what's under the hood.
It was a good point to make. It's also worth mentioning that ESO's large scale battles were designed to be more dependant on your processor than your GPU, so people that opt to go with a cheap processor and one or more top-of-the-line GPU's (which works for most games) may find ESO isn't running as well.
