if i use a cpu/mobo with pcie gen 5, such as ryzen 7000, can i still take advantage of the increased bandwidth when sharing lanes between older cards (gen 3/gen 4). if i have the 3080ti (or any future gpus) in the server using 16 lanes will the remaining 8 lanes end up locked at the slower speeds when sharing the lanes between the remaining 3 cards, or can i take full advantage of the increased bandwidth even if the cards are not actually capable of running at gen 5 speeds? if the shared lanes are going to end up being locked to the slower gen 3 speeds thats not a great solution as my 10gig fiber card would still be limited by pcie bandwidth (which is part of the reason im upgrading from the 6850k which only supports pcie gen 3) only now its also sharing that limited bandwidth with the sound card and the raid card, slowing things down even further.
