performance-wise, for video editing, what i can say is that: the pc mounted with this graphics card and an i7-14700 gives me a video timeline under Kdenlive that's around 4 times longer or more complex than under my barebone i5 13th with integrated graphics card. compression is noticeably faster, even if i'd hoped for more to see the size of a mounted pc compared to the size of the barebone.
4k screen not tested. multi-screen not tested either. but by feel, I doubt I'll have a graphics card that's a thunderbolt.
As for the smell, I suppose it's the motherboard that's the source of the problem, but maybe the graphics card is involved? from the moment I turn it on until it goes out, the mounted PC emits an unpleasant chemical smell, not thick but unmistakably present. and that's despite the fact that I'm buying + 3 months.
