I'm thinking, since prices on the 11th gens are coming down, of doing a (somewhat) superfluous upgrade. Currently I have a 10900K, on the Extreme XII motherboard, along with 4 TB of PCI-E NVME on the DIMM.2 riser (2 2tb Samsung 970 Evo+s, which support PCI-E 3.0) . The problem with this is it puts the 3090 TUF OC I have into 3.0@8x, since the DIMM.2 takes up some of the PCIE lanes.
Everything I've read leads me to believe that the Extreme XII supports PCI-E 4.0, and my questions would be:
Am I correct in my information that the Extreme XII supports 11th gen @ PCI-E 4.0? I know it supports the 11th gen (and I'm on the BIOS version that does so, I updated to enable resizable BAR), but I'm not 100% on whether or not it supports PCI-E 4.0. The second question would be if I made this upgrade (the 11900k's are close to 300USD now, so it's not a terrible price) would my GPU get PCI-E 4.0@16x, and the NVME get the 3.0 speeds?
If the upgrade would still leave me at 8x on the GPU, I'd see little/no purpose (although supporting 4.0 @ 8x would still be plenty more than 3.0 @ 8x).
Yes, I know this is a monumentally superfluous upgrade, however the goal in both building the PC, and this one (last, for the foreseeable future) upgrade would be future proofing the PC to last a solid 8-10 years with minimal upgrades for a long while.
Also, it offends me everytime I see a 3090 running on 8x when I paid NewEgg Shuffle levels of money for the damn thing...
Thanks!
