Not really?

Any current GPU that has a free driver isn't bottlenecked by PCIe 2.0 bandwidth even pushing 2560x1440@120Hz, so I'm not sure what practical use PCIe 3.0 has.

I thought the raptor boards supported PCIe 4.0, but I guess the blackbird model would only support 3.0.

I've read something about limited amounts of PCIe lanes being available despite all the ports, but I haven't run into any problem myself.


Sure DDR4 is higher bandwidth than DDR3, but DDR3 has a lower latency - I'm not bottlenecked by my 128GB of DDR3-ECC either.
