My GPU just broke and im looking at the market right now and im planning to buy either Asus EAH6970 or Asus HD7850 / HD7870.
However they both require a mobo with PCI2 3 and PCIe 2.1 but my motherboard Asus P7P55D-E PRO is only PCIe 2.
Will these cards work on my motherboard?
by the way my CPU is kind of old too Intel i7-860.
If these cards are not compatible hope you guys can suggest a card that performs a little closer to these with same price range or lesser but not much power hungry. :-)
