This is the quote for the MSI R7970-2PMD3GD5 Radeon HD 7970:
"The MSI R7970-2PMD3GD5 Radeon HD 7970 Video Card has a PCI-Express 2.0 x16 interface, compatible only with motherboards bearing the same interface."
The entire sentence seems wrong to me. Aren't all 7970s PCIe 3.0... and isn't PCIe backwards compatible?
