Have I saturated all my PCIE lanes?

Just wondering whether I may have overdone things? I have 2 x NVME PCIE SSD (4x and 2x PCIE speed) and PCIE WiFi (in 1x slot) and 8GB Sapphire Pulse Radeon RX 580 (16x PCIE).

According to specs, my H370 only has 20 PCIE 3.0 lanes... and when using Windows, parallel copies drops both transfers to as little as 10MB/sec (to NVME!!!) even NVME to NVME copies run at this speed if you start a second copy!!!

I assume this is the case because I have saturated the PCIE lanes?!

It doesn't happen much under macOS, but under Windows, it is VERY noticeable.

Please remove this post if it is too off-topic!
