according to the X38 article on toms this is the new specs of PCIe 2.0:

PCI-Express 2.0

Where PCI Express is concerned, the X38 has an advantage over all of its competitors: it is the first chipset to support the PCI Express 2.0 standard. However, this only applies to the two x16 PCIe slots - the four x1 slots and the single x4 slot are attached to the South Bridge of the ICH9 and are therefore still limited to PCI Express 1.

With PCI Express 2.0, the frequency of the serial pathways doubles from 2.5 GHz to 5 GHz, giving each PCIe lane a 500 MB/s transfer rate. This is true not only for the graphics card, but any component that uses the new interface, be it a network controller or a sound card.

By the time cards appear that are actually able to utilize this bandwidth, Intel will probably already have introduced newer chipsets. Thus, at this point the PCI Express 2.0 interface is a nice addition, but doesn't really contribute to future proofing the board per se.


does this mean even 1 video card by itself not in crossfire mode is also faster than in a PCIe slot in a P35 mobo?..

the reason i am asking is because i do not know the specs of the old PCIe slots..

thanks to anyone who replies

wrong section sorry, should have been in the general motherboard section.

please close this mods..

tnx

HA HA punked

no, pcie x16 isn't even fully used yet.
