Hi i am currently thinking about upgrading my computer and as i was looking threw video cards and motherboards i notice this new pci-e 2.0. Does this mean i have to find a new board that supports pci-e 2.0 slots or is this just something to with the the video card byitself and it can go into any pci-e slot on a pci-e motherboard.

It is a new thing but it isnt a problem the card is compatable with both standards of pci-e its basically backwardsly compatable.

No you have nothing to worry about. Even the best cards dont currantly use the full performance of a pci-e 1.0 slot yet.

The 9600GT. So does this mean if i buy a pci-e 2.0 card it will not run at its intended Gpu speed, pipeline, memory speed, and Memory bandwidth? Thanks again.

9600 will run fine on a pciex16 1.1 slot. it will run at its full potential in all aspects .
any improvement you see in mobo's sporting pcie 2.0 is due other components ( like northbride,southbridge etc.. ) and not due to the higher badwidth offered by pcie 2.0

Thank you Sagargy. I have one last question that i noticed with this video card which is the power source. From the pictures i have seen they changed the plug to this different 6 pin power connected that splits into 2x4pin power plugs. My question is do i have to plug both those 4pin plugs from my power supply or is only one needed to be pluged in for the graphics card to work sufficiently.

You will need 2 of the 4 pin molex plugs free from your PSU to plug into the back of your card. I should think this adapter will come free with the card when you buy it.
It won't work with only 1 molex plug attached.

Hope that answers your question.

If you use x-fire it is faster on a pcie-2.0 in most cases. Other then that no. On the same note there is little to no point in buying a MB atm that is not 2.0.

So, then would a PCIe 1.0 card like the 8800GTX run just fine in a PCIe 2.0 slot and just not take full advantage of the 2.0 capabilities?

correct. There is really no advantage to getting a PCI-E 2.0 slot right now, and even when everything is up to snuff in the latest PCI-E 2.0 department, I doubt that there will be any major increase in performance from 1.1 to 2.0. I asked this same question a while ago too :)

The main thing that benefits a 2.0 card going in a 2.0 Motherboard is the added power it will get from the Motherboard,meaning it wont require as much if any in some cases extra power from molex or 6 pin cables.
