PCI bus and BlackMagic devices

Hi, I have an Intensity Pro + a Decklink Extreme 3D installed in my MacPro 1.1 2x2.6 DualCore. Can it be that the PCI bus doesn´t have enough power to capture HD streams via HDMI from both? I get lag, choppy pictures, frame drops, tearing, all sorts of trouble, when both cards are in use.
