While I don't see the reason to upgrade as an existing Rampage VI Extreme owner what worries me is that I see a trend toward "cheaper" in ROG products.....
This does not look as premium as the previous model unless it is indeed a more cost effective version. The armor is less complicated, has less lighting the PCI-E slots are also less (I know they were not all 16X) while all the indium plating and fancy effects are gone.
The original was really something else, this one is.......well meh.....
Well that really depends on what you are looking for. One could argue the design is less flashy and more functional.
The premium is under the hood with the extra capacitors and heat dissipation. The cover over the M.2 drives was replaced with a metal one with heat pads over the M.2 drives. That is definitely an improvement over the plastic shrouding which could inhibit heat dissipation.
I also get a couple extra USB slots on the back (sorely needed) and I can do some interesting things with M.2 drive slots when the prices come down a bit more and capacity increases. In this case they included the bracket with heat sinks. I only recall seeing a basic bracket with the original.
Personally, I have a case with LED lighting and a CPU cooler with lighting. So the loss of some lighting is not a huge deal. Also, I only bought this refresh cause i killed my rampage socket when upgrading to a 9th gen CPU (an unfortunate thermal pate on the pins incident).
Do I regret upgrading to this board? A bit. But a lot of that has to do with what happened to my old board which was rock stable out of the box. This one has some issues which still need to be ironed out.
