PCI-e 3.0 compatibility Tags: Graphics Cards Gtx Compatibility Pci Express Graphics Last response: February 3, 2012 4:06 PM in Graphics & Displays Share Brockavich February 3, 2012 2:10:31 PM So... I have been waiting patiently for the GTX 600 series to show itself, this after the GTX 580 I bought literally exploded. Anyway, I had a horrible thought. The new series cards are PCI-e 3.0. I'm pretty sure my mobo (P55A UD3) only supports 2.0/2.1 So, this is probably a dumb question, but will a PCI-e 3.0 card still work in my machine? Or am I going to have to upgrade to a new mobo/stick with the GTX 500 series Thanks guys More about : pci compatibility | E-mail me updates | Report abuse Register or log in to remove rwpritchett Graphics card Expert February 3, 2012 2:19:33 PM No worries, PCIe 3.0 card will be backwards compatible with PCIe 2.0/2.1 slots. | Report abuse Rockdpm Graphics card Authority February 3, 2012 2:26:34 PM Yes, they even announced it on unboxing's .
