1. does PCI express meaning PCIE 1.0???

it means they didn't specify.

2. does PCIE generation 2 same like PCIE 2.0???

probably. ask the marketing droids that wrote that. the formal name is PCI Express Base 2.0 specification

3. what is speed on following:

http://en.wikipedia.org/wiki/PCI_Express#History_and_revisions

PCI-E 1.x is 2.5GT/s and 250MByte/sec burst transfer per lane.

PCI-E 2.x is 5GT/s and 500MB/sec burst transfer per lane.

4 lanes are capable of 4 times that, 8 lanes, 8 times that, but each lane can function independently, and its up to the card and its driver software to dettermine how to utilize the lanes.
