It just mean it may not be as fast as the card are capable of performing.
My Motherboard -->http://www.gigabyte....ge.aspx?pid=... GA-P55-USB3
my motherboard says 1 x PCI Express x16 slot, running at x16 (PCIEX16) (Note 2) (The PCIEX16 slot conforms to PCI Express 2.0 standard.)
===>Does this mean mean that I can't use Graphic cards with Interface PCI Express x16 3.0 ? but only PCI Express x16 2.0 ??
Can u tell me which of these 3 graphic cards can run with my moterboard ? 1)Gigabyte GeForce GTX750 Ti 2GB WindForce 2X OC (GV-N75TOC-2GI) or 2) VTX3D Radeon R9 270 2GB X-Edition ,(both 1,2 are PCI Express 3.0 ) 3) GeForce GT 730 this one is PCI Express 2.0
Thanks
