PCIe 4.0 specification released

Hard find a case where speed limitation hit current users.
Latency, yes, it could be better.
 
Eh. I'll be upgrading from PCIe 2.0.

Looks like Cannon will support it. Will be upgrading next year.
 
Why would you jump on PCI4 if PCI5 comes 2019, what different in todays workload will >PCI3 make?

I'm sitting with a 2600k oc'd to 4.6gHz. Looking to upgrade the CPU,Mobo,Ram next year. Haven't upgraded in 6 years.

It's certainly important for high speed networking (tightly coupled HPC), FPGA to CPU interoperability, and for GPU computing. There may be benefit in some games or future games, but very few are limited by host to GPU bandwidth. Possibly high resolution video processing too.

Hence skip pci4 and wait for pci5

PCIE express 4 was announced in 2011. PCIE 3 in 2007. It took years to nail down the final revision, you likely won't actually see any mainstream PCIE 5.0 hardware until 2022 or so.
