I'm looking to use a riser to mount my GPU but I've found that some brands label their cables as PCIe x16 3.0 vs just PCIe x16 (for example this one by Thermaltake is 3.0 https://www.thermaltake.com.au/tt-premium-pci-e-3-0-extender-300mm.html) . I was wondering if there were any difference between the 3.0 cables and standard PCIe x16 cables? Thank you
