Hey guys i just need to know if ATI video cards or compatible with Nvidia mobo? I just recently bought a HD 5670 and that didnt work, and with conclusion from 5 experts, they say it was that my PCI-E x16 wouldnt work with PCI-E 2.0. The day after i bought that i returned it and got a crappy Nvidia 9500 GT, along with a new power supply. That video card worked fine but it wasnt close to my expectations, so i then returned it for an ATI HD 4830. Now im back with the same problem as video card one. what should i do?
i know its late to add, but to anyone that needs help with this ... you probably need to clear your cmos. i had this problem with nvidia cards only being seen by my mobo (asus m4n68t-m v2). asus customer service even told me pci-e 2.0/2.1 cards were not backwards compatible with pci-e x16 (ie pci-e 1.0/1.1 etc...) slots. i had to school this "tech" that my 9800gt pci-2.0 card worked fine, and the hd 6790 i had installed at first worked fine till swapped cpus then i quit being recognized. then the hd 6850 i bought to replace it wasn't recognized by the board . i later figured out that i just needed to clear the cmos (still using the 6790 i thought i ruined on another computer )
