  1. Hello guys, i have a Biostar GF7050V-M7 motherboard, and i am buying a Diamond ATI Radeon HD 3870 videocard, but it says that it requires "PCI Express 2.0 X16" and my Mobo only says that it has a "PCI Express X 16" slot, will this videocard work in this Mobo? or what is this 2.0 version thing?

    PCI express and PCI express 2.0 are backwards compatible, so should work fine. I believe it requires 2.0 in order to take full advantage of extra bandwidth available with a 2.0 slot. So it should work with your motherboard, albeit with a slight limitation on the bandwidth there. However, there are rare circumstances reported where pci 2.0 video cards have difficulty on pci1 slots.

    So I guess the answer is "probably"

    Yes it works, I have a PCI express 2.0 VGA card and my mobo can only support PCI express. It works, but it will not get to take advantage of the extra bandwidth.
