THoughts?

Looks like a fine build.

Again, though, I maintain what I said above about the PSU. The 900W unit I point you towards above would be plenty, and the most you actually need here is a 1KW unit.

Of course it's your money, and there's no real harm in using an overpowered unit, but ... the money could be put to better use upgrading somewhere else in your build is all I'm saying.

EDIT:
In the 1KW range, I like both these units quite a bit (the OCZ is a great deal ATM after MIR):

For two 6990s in Crossfire, they recommend a 1000W peak-rated unit. For two 6970s, they would recommend either a 650W or a 700W peak-rated unit (their site doesn't say, but I know from experience).

So I maintain that a high quality 750-850W power supply (maybe 900W) is plenty because any high quality unit that we recommend will have a continuous rating, not a peak rating.

I think that this is probably about the best 850W power supply on the market right next to the Corsair AX850 (so, it comes down to the price between the two as well as the looks - if looks are important to you).

Can you explain the whole 6970+6990 thing to me? I know the 6990 is a long card, so what case can fit it? and do I need to use the BIOS switch on the 6990 when i CF it to keep the same speed as the 6970?

I don't know anything about these specific details.

The only real reason I could see needing a 1000w power supply is if you were adding a lot of other things to the build. When I say this I mean running a bunch of SSD's and HHDs, also adding a bunch of fans and a water cooling unit running 2 or more pumps. Now if you plan on going water cooling down the road then yeah I could see that. But there are a lot of people running what you have on less. But it is your build and there is nothing wrong with to much, its just not necessary. Just don't get a 500 watt power supply, lol...

You are not running a lot of add-ons so its not needed but then again if you decide to add another gpu down the road then that 1000 watt power supply will be of some use. Going with that would be future proof for expanding and that is really about it.

I use a power supply that is way to much for my system but I got it for a deal and now I have to buy a new one because I got what I paid for. Now I just need to find one that fits my needs as I'm going to be adding another gpu and want something that has 2 8pin cpu power plugs. But that is going off topic, so I would get what you think will suit your needs. Most people use there power supply through multiple builds and if you think you may go 3 gpu cards next time or add a bunch more HDD's or SSD's then it would be nice to have that extra power.

Yeah, the 6990 is huge, around a foot long IIRC. The HAF-X will fit that card I'm almost positive, and it should fit in most full-sized towers. HAF-X is a GREAT case, too, so if you're already inclined towards it ... get it. You won't be disappointed.

However, you might want to start a thread in the AMD/ATI section about the specific matter of the card size, that might get you some more-informed responses than you would get on this thread. You could probably also just do a bit of googling, as there may be some 'official' list somewhere out there.

You needn't worry about the details of clocks and such on those two cards. They'll work fine if you just plug them in, the drivers will handle the clock differences automatically.

Most likely though you'll want to go ahead and manually OC (and perhaps OV) both cards using something like Afterburner, so the 'stock' clocks will become basically immaterial.
