Taking center stage among the other enhancements planned for PCI Express 2.0 is a doubling of the bit rate to from 2.5 gigabits per second to 5 Gbit/s. But there are also a number of planned improvements in the works for both the protocol and software layers of the architecture as well.
In addition to connecting with plug-in slots, the PCI Express Cable specification will allow PCI devices to connect using copper cables as long as 10 meters long, and with data transfer speeds of 2.5 Gbits/s per line.
According to PCI-SIG, the base 2.0 specification will be backwards compatible with all existing PCI Express 1.0 and 1.1 systems, supporting both 2.5 Gbits/s and 5 Gbit/s signaling rates.
So this means that video cards are going to be getting a nice upgrade soon? I guess we'll have to wait.
