| you will need a lot more than 1000W of power. you should budget at least 1200W RMS to power the GPUs alone, so i would recommend going with a 1500W or 1600W 80plus Gold or Platinum-certified power sup... |

| Actually, i just thought of a pretty good way to determine what the reference design looks like: just go to AMD's website and look at the picture of the card :]

| I'm really surprised that you needed to put Accelero coolers on 5870s, especially when you had that much spacing in between them. I like your setup there though, that's pretty slick! |
