Does anyone here have a link to a review of the upcoming B580 GPU on PCI-e Gen 3? I know this GPU is physically linked to 8 lanes only, so Gen 3 x16 wouldn't help even though the throughput would be similar Gen 4 x8.

Any Review(s) of Intel Arc B580 GPU on PCI-e Gen 3?

That's a fake video, released before Battlemage drivers were even available.
A bit more usefully, this vid includes a test with an Intel 10th gen system which only supports PCIe 3.0.
It shows in the worst case a 16% performance drop in Cyberpunk at 1080p RT Ultra, FSR Quality, when compared with a 9800X3D system. Unfortunately that's a big CPU difference skewing the figures too, but I haven't seen anything better.
it is disappointing that reviewers haven't looked into this as there will be many potential purchasers with PCIe 3.0 systems. I have seen in an apples-to-apples test with a Radeon 6600XT (another PCIe 8x card) that Gen 3.0 was sometimes within margin of error but in the worst case (Doom Eternal) about 20% performance hit.

Not sure if it's worth upgrade to a better AM4 motherboard to get PCIe Gen 4 support just for a few extra FPS, though it shouldn't be too expensive if I resell the board. I'd probably wait until the B580 limited edition gets restocked and buy that first to see if it's worth the effort.
Would it not make more sense just to get a different GPU? The GPU is excellent for it's price take that away i'd just get something else
I want to try Arc out and see what's the fuss about now that the driver isn't as bad. Not much more reason then being curious.
I had the same feelings with an A770. I had very few issues and looking at the B580 reviews they seem to have hardware fixed the big one (poor UE5 performance).
