I am looking at getting the rampage III extreme since it is one TANK of a motherboard. The only thing is I do not know if I will be able to use Zotac Amp! GTX 480s in SLI on the board. The Amp! cards are good since they are far faster, quieter, and cooler than all the other GTX 480s, especially EVGA's offerings.
Though with all the extra fans I'd have to have one on PCIe 1 @x16 and the other at either #3 or #4, hence the problem: I don't know if the card on #3/4 would run at x8 or x16. If I had to have one run at x8 I'd be pissed since it would suck to get a major GPU bottleneck on $510 cards.
If anybody can shed some light on this I'd greatly appreciate it, as I plan to purchase the parts soon.
my concern is not adequate space between the cards. I mean this in two ways-- 1. they will be up against each other. If you look at the cards, they have 2 side mounted fans which brings us to 2. they need space for air flow. So If not in slots 1,2 @ x16 then what about 1,3 @x16?
Besides airflow, everywhere I've looked has said a single card covers more than one pcie port. Actually it almost covers three. Look it up please. Or just answer this : will ports 3 or 4 go at x16 if I have #1 at x16? That's the only thing holding me back from making this purchase.
