I will soon be upgrading at the end of the month, i am considering LGA PCI express mobo and a GF6800 gt PCIe card, LGA 775 P4 3.2.

I know nothing about PCIe as have been out of the loop for a few months, are there any issues i should be aware of?

Hi,

I would start here: http://www.nvidia.com/page/pci_express.html

Others probably have some experience also, I haven't used it yet.
