For someone who knows how the tech works, what difference would adding 4GB of GDDR5 make and will it be a worthwhile difference? If not, what would they need to do to get it to 5TF?
I'm hoping whatever it is they do, they are able to keep the Neo at $449 at the most.
Edit: just read up how to work out TF and roughly what Sony would need to do to hit 5TF. The RAM won't make a difference.
