I have an opportunity to get a really good deal on a system upgrade. I was hoping to pick up the following: AMD64 X2 4400+ TWO GeForce 7900 GTX cards to run SLI I need a good motherboard that can support that. I also have 2 gigs of dual channel RAM and a Sound Blaster Audigy X-Fi FPS edition, and a TV tuner card. So yeah, I need space for two GeForce 7900 GTX cards, a big sound card, and a TV Tuner. Anyone have suggestions on the motherboard that can fit all this?
