PCI-E 2.0 is technically twice as fast as 1.0. To quote wikipedia's article on the bus spec:
"PCI-SIG announced the availability of the PCI Express Base 2.0 specification on 15 January 2007. PCIe 2.0 doubles the bus standard's bandwidth from 0.25 GByte/s to 0.5 GByte/s, meaning a x32 connector can transfer data at up to 16 GByte/s for both videocards (SLI 2x etc). PCIe 2.0 has two 32-bit channels for each GPU (2x16), while the first version only has 1x16 and is operating at 2 GHz."
