HUB now have their review up, IMO LGA 1700 is now effectively a dead man walking, given that no more CPUs will release on it, I can't see mobo makers putting time into new boards or adding new support/features into BIOS updates etc. I think the next round of CPU releases from either side will make me decide if I go Ryzen or just slug stick it out with the 12700KF until a time comes where the CPU isn't enough to power through games with the 4090- That time seems unlikely to come around this side of the next 5 years so I guess naturally I'd be looking at an established DDR5 build then anyway. All of my productivity tasks are GPU accelerated now, the CPU simply has to idle along, so the reliance on the latest CPU is trivial at best.
If one thing is clear to me, the Alder Lake platform now that gigabyte has had a stable BIOS for a year, has been excellent and will remain excellent, and mine is DDR4.
With 12th gen we reached a level of performance that really for the most part, only those chasing every fs even if it's single digit vs the last gen, would upgrade to, otherwise the extra cost makes no logical sense.

Damn I was writing my post whilst you posted that same vid!
