PCI-E 1.1 16x versus PCI-E 3.0 16x

This screenshot shows that my GPU supports PCI-E 3.0 16x, and that it's running PCI-E 1.1 16x. Does my motherboard model determine what version of PCI-E is used? Also what performance difference would I get from it if it were running on 3.0 16x? Thanks in advance.

as far as i know, PCI-E slots are backwards compatible so it doesn't matter if you are using 1.1 slots. Yes the mobo determines which is used. The only thing is, is using a PCI-E 3 slot will get you better performance but not by a huge amount so it will be fine for use.

Your card is running in 1.1 because its idle. Click on the '?' and than on 'start render test' and it will change in pcie 2.0 or 3.0.

Ahh thanks, it changed to 2.0. Will it being 2.0 and not 3.0 cause much performance issue?

It's more of a difference than i thought.

Base Clock Speed: PCIe 3.0 = 8.0GHz, PCIe 2.0 = 5.0GHz, PCIe 1.1 = 2.5GHz
Data Rate: PCIe 3.0 = 1000MB/s, PCIe 2.0 = 500MB/s, PCIe 1.1 = 250MB/s
Total Bandwidth: (x16 link): PCIe 3.0 = 32GB/s, PCIe 2.0 = 16GB/s, PCIe 1.1 = 8GB/s
Data Transfer Rate: PCIe 3.0 = 8.0GT/s, PCIe 2.0= 5.0GT/s, PCIe 1.1 = 2.5GT/s

Its running at 2.0 because your motherboard or your cpu doesnt support 3.0. You wont notice any performance difference between pcie 2.0 and 3.0 with single gpu.

no bottlenecks below a GTX900 series, between 2.0 and 3.0 and that was the last analysis I saw, 1080's might be a problem, a 390 wouldn't be.
