stkhawk,
Not sure why you are crowing about this. You are aware that Sapphire Lake has been delayed more than once right?
I think your own info about the early reviews of using DDR5 in gaming are pretty indicative that there isn't a market-based NEED for DDR5 in PC's yet....so the fact that Intel is introducing a desktop CPU that supports DDR5 is pretty much meaningless in terms of the market.
Do you expect the primary DDR5 demand to come from the PC market rather than the server market? I don't...and I would be surprised if you did either.
