If you look, I do a lot of non-gaming tests as well. Yes, gaming is a big focus, but it's not the only focus. And I also have to consider the fact that, barring a 5090 Ti or Blackwell Titan, this will undoubtedly be the fastest GPU around for the next two years. How can the fastest cards around with new features that will probably be sold out warrant a 3-star score (as someone else suggested)? That's ludicrous to me.
This is an amazing piece of hardware, even if it's not 50% faster than the 4090 in every scenario. And that performance right now is clearly a product of early drivers. These are literally the first public (ish) drivers for 5090. Nvidia internally can't test everything, and bugs and issues will slip through. The 9800X3D vs 13900K results prove how messed up things can be at times. Do I dock half a star for what will inevitably be a relatively fleeting problem? Again, I don't think that's warranted.
(Intel's driver problems are a different story, because we've seen the same things again and again for over two years. New games come out, we get some oddities. But the 4090 and 4080 Super worked fine with these drivers and it was only Blackwell having issues, and not even consistently so. I anticipate fixes will come in the next month or so.)
As you properly point out, value when you're looking at this sort of hardware is incredibly subjective. If you ONLY care about games, with zero interest in AI? Sure, it's probably a 3.5-star card because it's very expensive for relatively minor performance gains. More heavy RT testing will show larger gains, though, and that's what I'm currently working on doing.
Framegen and MFG are going to be very subjective as well. My personal experience with framegen is that you need a base framerate of 40~45 for it to feel "good" — meaning 80~90 FPS after framegen (and without framegen you'd probably be getting 55~65 FPS because FG only adds ~50% on Nvidia). If that same rule of thumb applies, we'll need MFG to provide 160~180 FPS, which means you'll want a 240 Hz display for it to be "useful," even on lower tier 50-series GPUs. I don't think a 5070 is going to do 4K at 160+ FPS without performance mode upscaling, though... but DLSS Transformers maybe makes that less of a concern.
Anyway, initial testing out of the way, I'm now poking at MFG and DLSS 4 stuff to try to determine what is and isn't a good experience. Stay tuned... that page six needs a lot of additional testing and data! 🙃
