Over the last two days I put together my first complete system. I purchased an Asus P6TD Deluxe motherboard and two of the newest video cards by XFX, its the 5970 (597X PCIe 2.1 edition). Although the motherboard only has PCIe 2.0 listed, I read that 2.1 should be compatible. I install in my video cards, and boot the system up but I see nothing on the monitor. I've tried both video cards in three different PCIe slots.. I tried one card in at a time and I also tried two in crossfire. I have had to resort to my old PCIe 1.0 XFX 7800GTX to get a video signal. I updated the bios to the latest and greatest, and I was told by a friend that I would need to enable the video cards in the bios.. or disable something but I could not find what he was talking about and I'm stumped. Any help is appreciated.
