if you are interested in the NEC, I have one sitting in my basement, it was lightly used, its like brand new, I still had to use 20% brightness to keep the brightness down, it hasn't degraded one bit.
let me know if you're interested, I can go lower than $380 if you interested.
if you're interested in a 4970k delid that does 4.7ghz with only 1.25volts, never tried to go higher but I am sure I have a high quality chip, let me know if you or anyone is interested.
cant wait to see the difference from 144hz, it will be noticeable at first sight.
I kid, just being sarcastic, I don't think anyone will be able to tell the difference, unless, you're a hawk.
