I've been waiting for someone to do an updated version of this test: Using the latest high-end GPUs, how many PCI-Express lanes can you go down before your performance starts to noticeably suffer? Tech PowerUp! did this with a GTX 680 and Radeon HD 7970 at all PCI-Express versions and lane configurations

The answer: It's still at PCI-Express 1.1 x8/PCI-Express 2.0 x4 (or 2GB/s).
