I have an HP pavillion media center m7334n with a MS-7184 motherboard. It has 1 PCI-E 1.0 x16 Slot. I am looking to upgrade to a Nvidia GT 520 video card. Only problem is that the GT 520 is a PCI-E 2.0 x16. Now what I wanna know is if the PCI 2.0 card is backwards compatible with my old 1.0 motherboard? Meaning Fitting & Technically. Thanks for your help
