Question about MSI GeForce RTX 3080 Gaming X TRIO 10G

Perfomt 1A as said 1% less than 9900k and 5% than 10900K I think the big difference will come with PCIE4 and the Intel 11 series.

I can tell you how it runs tomorrow, then mine should arrive. I have the 9700k myself, I think maybe 1-2% slower than with the 9900k, maybe even equivalent. From my point of view it's more the latter.

Moderately good, PCIe 4.0 is recommended, which the i7 9700k does not support, but it should still be compatible.

Yes
