I remember a time seeing 1200 or so...that may have been a beta, and it was more than a year ago so......irregardless it truly does not matter other than in terms of input...the human eye has trouble based on how many times a second it "absorbs" an image....I cannot see the difference between 60 and 512..but from 30-60 it is quite noticeable....again though this WILL affect input and responsiveness.
