Aye. The best scaling I've ever seen with three of the same card would have to be either the 4770s I had in TrifireX or the three 5770s. It's a toss-up between the two but both do very well. It would seem that the 128-bit bus cards scale a LOOOOT better than the higher bus cards do.

Just get two 6970s and you'll be happy as can be. I want a 6950 to be honest... but I need a case to fit one in... ^^

This translates into a 26.4% performance increase compared to regular P67 motherboards with similar SLI configurations, as measured by 3DMark06. For CrossFireX, the P8P67 WS Revolution supports up to quad GPUs builds in PCI Express X8 links, unlike standard motherboards, which lack the bandwidth to do so."

If they were claiming 2x dual GPU cards for Quadfire they would of mentioned them running in 16x mode as anything 3 cards and over you start seeing 8x Pcie.

Why exactly won't the WS handle 4x GPUs when the manufacturer clearly states it can? I'm not trying to be a **** but it seems unlikely that it won't work.

I've decided to go 2x 6970s with 8GB of RAM for now as I've just read a review that claimed quadfire 6970s get into 100C at stock. I have plenty of time over this next Summer/Fall to upgrade.

it supports 4 GPUs, but they will not run in crossfire. I really could be wrong, but judging from the newegg page it only supports 3 way

Wow, thank you very much for saving from my disappointment. That is bewildering that it won't work but I suppose being a WS board people don't crossfire for GPU accelerated apps.

The ASUS SABERTOOTH P67 looks appealing now along with a 7 year warrantied AX850.

Which would be better? The H70 or a NH-D14? If they offer similar cooling performance then a air HSF should be more reliable and strangely the Noctua fans match the tan/military look of the motherboard.

The RV02 supports a 3x 120 internally mounted rad. If I needed more I can mount a 4x 180 rad to the side and make use of the water cooling grommets. With 2x 6970s they are going to be spaced a slot apart so intakes are going to be clear. The ASUS 6970s have aluminum covers so it should help a little. RV02 has 3x 180mm mounted fans at the bottom and only 1 120mm fan at the top. Correct me if I'm wrong but the 3x 180s should provide positive pressure in which should help force air through the 6970s and through the NH-D14 since it is in the air streamline. I can add a small fan on the Sabretooth's cover which will drop MB temps greatly so no issue there.
