The OLED panels internally run at 960hz, so I don't thing they will go down to 144hz OLEDs at any time. I think they will just improve the scalar until they reach 960hz and then all OLEDs will be in the 360-960hz range. First gen QD-OLED was 165hz, but that is behind us, and will stay behind us.
Windows 11's AutoHDR is pretty good for a "fake HDR". Especially for bright/metalic objects it works perfectly.
For shadows, not so much. It shows the 5 shades of black available in the SDR signal "perfectly" as well, you can see each and every one of them separately.
That is a trivial warranty replacement. We already have a system for it. Also, both motherboards and GPUs have 12V to 1.1V VRMs on them. That is what the VCORE, VSOC, and VDDR voltage planes are doing, taking 12V and turning them to local voltages. Now all that will happen is you will get VUSB...
Because you are replacing a single VRM in the PSU with 4-6 small 10W VRMs, which are basically a single 50c mosfet on the motherboard. The voltage conversion chip is literally cheaper than pulling power all the way from the 24 pin connector. The PSU has a single high quality 5V 100W power stage...
You are underestimating how much 12VO simplifies the PSU design and the number of things that can go wrong on a system. 12VO turns the PSU into glorified laptop power brick, and all the complexity of dealing with lower voltages goes to the motherboard. You won't need a seasonic PSU for stability...
For Zen 3, 5 GHz turbo is nothing. The 7950X has 5.7GHz. It can probably do 5GHz on multiple cores as long as they are on separate CCDs.
Also do consider how AMD counts "turbo clocks", the 7950X 5.7GHz turns on for a couple of miliseconds. After that it drops down to more like 5.3-5.4GHz which...
1900$ for a 5120x1440@240hz OLED screen with amazing HDR? 1900$ is a fine price for that. It literally has every feature, the only thing it is missing is a low persistency mode, but hey we just got OLED in monitors last year.
It will be a G9 OLED, 5120x1440. This has already been anounced on CES.

There is no reason for 1% lows to suffer. It isn't an MCM in the traditional sense where there are two GPU cores and separate memories working on separate frames. This is multiple dies working together. Think zen 2 chiplets vs two-socket servers. In two socket servers the NUMA-ness of the system...
Just wait it out for a week or two. The talk is that there are hundreds of thousands of 4090s ready for sale. All the scalpers will lose a heck of a lot of money.
Or wait out the 7800XT and 7900XT in december, you might even get a discount on a 4090.
