Hello I just got this Ati radeon 4870 Pci express X16 2.0 video card, my question is i think my motherboard pci slot is only a PCI Express x16 1.0 , Is there a really good program that will tell you for sure what kinda slot you have? If its only a 1.0 then im going to upgrade my motherboard so i can get the full potential outta my card.
