    Basically what he is saying is : the monitor performs decent with the highest overdrive mode at 140 hz, but the lack of variable overdrive makes it close to unusable at 60 hz, where the response times are both too slow and there is alot of overshooting.

    So if you can run all your games at 140 fps, then you will be fine, but i know i will be running alot of games at about 60 fps.

    Maybe for a monitor professional they can tell the difference, to me it looks mega smooth throughout the whole range, maybe same as peeps who argue over tenths of a FPS with RAM timings.

    It's probably a waste of time spending any further time talking about it, since you don't understand the terms.

    But as said, glad that you are happy with your purchase :)

    There are rumours that the 30 series RTX's might get DLSS3 support.

    If 30 series gets it 20 series will too but i think it will stay with 40 series only.

    I will, it just won't be as fast as by 4000 series, because it's missing this new SER function and other bits show bellow in pic



    I think older 2000 series will work too, but much slower since RT engine isn't effective like by 3000 or 4000.

    By one of the videos there was a comparison how crippled RT/tensor cores were by 2000

    Does not reflect in real world as raytracing performance of 2080ti and 2080s are very similar to 3070 and 3060ti.

    there are no such rumors, just people making things up.

    he said 25% boost with 3rd gen rtx, so if dlss2 does 62fps in CP2077, and dlss3 108fps, then I guess on 2nd gen it should be ~ 80fps, 1st gen will be limited more, it should still benefit more then with dlss2 upload_2022-9-25_17-0-50.png .

    Issue is image quality not just performance. They specifically stated the quality/accuracy of the optical flow accelerator was increased. And even with that early signs make it look like the quality is crap lol

    It's not RT it's tensor. Ada has a bunch of additional hardware functionality for tensor, on top of a straight up performance upgrade. Unknown if the interpolation utilizes any of it.

    I thought it was 150W per PCI 8pin so if an adapter has three cables then it's rated for 450W load. If the 4090 is an OC version then you get a four cable adapter...right?

    Correct, but we are talking about the corsair cable, which only uses 2x pcie 8 pin for 600 watt 12 pin.

    But yes, the included adapter will use 4x pcie 8 pin (but i wouldn't personally use that adapter).

    Oh, right! I'm also wondering how strict Corsair is with their requirements. They say 450W required a 1000W PSU but according to nVidia (and some 3rd party card manufacturers) 850W is enough.

    You deffo don't wanna use a 850w psu with a 4090, and extra deffo not a 4090 strix... power spikes from 3090 strix is enough to get "bad" 1000w psus to cut power.

    Transient spikes were fixed in 4000 series. Just like Nvidia recommends, quality 850W PSU will be fine. Don't spread FUD. (as for Strix, PSU requirements for that aren't yet revealed).

    I will believe it when i see it officially tested by independent reviewers.

    The graph you are showing is just nvidia promo that techpowerup posted in an article - they haven't actually tested it themselfs... and i take nvidia promo material with a truckload of salt.

    A good 850w PSU should be fine with 4090 but it is cutting it a bit short.

    With a 4090 and a 7950X system you're looking at 700 - 800watts when really you want your PSU to be at max 50% load or get a 1000w and be at 60-70% load.

    Me personally would buy a 1200w PSU for this system, which isn't ideal in the current energy market.

    I also think that a 850w PSU is a little short for a 4090, specially paired with a recent CPU from Intel or AMD, that are power hogs...

    In my opinion, the only way to make a setup like this work is to undervolt the 4090 and maybe even the CPU, to ensure both can fit the power envelope provided by the PSU.
