To my knowledge looking on other forums, its a mixed bag, some say they don't notice it, while others do. I personally think that if you are going to throw down that much cash, that the fix should be in place for this.
I have a 3008 A02 to my right and a 3007 in front of me. If you look for the lag you can detect it. I don't game so I don't care. If you are hyper about lag and will be annoyed if you can detect it, you will care.
