7970's hold the crown for heaven 3.0 right now.
So i hope that answer your question.
BTW i have owned both 7970 crossfire and currently 680 SLI.. No noticeable difference man.

7970 reference are loud as hell. 670's are dead silent.
So if your going to get 7970's DO NOT GET REFERENCE. thumb.gif

Mine runs perfectly fine, and I've read alot of reviews with these things with 2GB of Vram and they only get like 2fps more.

It's not about FPS man, modern day games these days, let me name a few....

Crysis 2
BF3
BC2

Upcoming games....
Medal fo honor: warfighter
Crysis 3
Battlefield 4

When you enable all the graphic options, that takes up VRAM and slows everything down. DX11 & Tesselation are extreme resource hogs.

You can't say 1GB vram is ok for maxxed out Cryengine 3 and Frostbite 2...

Thanks yeah, and loudness isn't a concern for me since i've got a 12k btu window AC 18 inches next to my ear lol. My 470s at 100% don't bother me smile.gif

As long as it's consistent loud sound that is, no high pitched or strange sounds that would be irritating.

Actually I can play Battlefield 3 on maximum settings with a minumum of 30FPS, usually around 40fps or so.

And to the OP, I agree about the reference 7970's being loud, like almost all reference AMD cards lol.
But if you don't mind it.. just be weary of coil whine.

I agree with the idea of 1 hd 7970 3gb of ram, I have an asus 7970 reference card, i put an arctic extreme cooler on it, flashed it with the ghz edition and get very good FPS I can only imagine what it would be like in CF but my CPU would bottleneck that.

There are lots of reviews out there showing that HD7970 GHZ edition is the current king of single Graphics cards obviously the 690 and 6990 are better but they 2 in 1 gpu's

Actually I've read that the 6990 isn't really that much better than a single 7970.

Well, it's a toss-up really.
But first off: do you think you need 2? My borther was running CF 7970s on a single 1080p and I told him it was a waste of money and energy. He eventually sold one and he's very satisfied now. He didn't expect a single 7970 to run BF3 that well. I personally don't see the point in maxing out AA in games because it blurs the image too much, especially in BF3 I notice it takes longer for me to pick out targets when AA is cranked up.
Whichever you pick: I'd get 1 at first and see how you like the performance. If the shipping is high you could get 2 off the bat but only install 1 and if you like it, send the other back in it's unopened package.

I've seen a lot of second-hand 7970 going for € 300 - 350 here so if you have that option I would go that route because that would definitely give you the most bang for your buck. (my brother got 2 Sapphires BNIB for € 325 each)
The ref 7970's are really loud IMO and a evga GTX 670 FTW looks better. But the 7970 3GB vram and bigger memory bus is nothing to sniff at.

I would get a 7970 if I was in the market for a graphics card at the moment because I would put it under water and OC it. Of course, getting a non-ref cooler would completely negate the awful noise they make but they'll dump their heat in the case (which can add up if you would have 2 7970's in your rig, but the HAF932 will handle it fine I reckon).

It's a really though choice but all things taken into consideration: the 7970 might be the better choice for now and the future.

EDIT:
In regards to the "1GB for 1080p is enough" side-discussion going on here: Don't just look at average fps. Min fps is very important as well since that tells you something about the time between frames. I read a good article about this once but can't find it ATM. Basically, average fps doesn't tell the whole story. Having more vram will certainly help against stuttering, sudden frame drops etc (memory bandwidth is also important) ergo making gameplay feel smooth(er). IMHO 1 GB is not enough for modern games at 1080p. I don't even understand why you'd buy a 6950 with 1 GB when the 2GB isn't that much more.

Yep I'm sure I want 2 for a few reasons, my SLI 470s are about the same power as a single 7970 and I want to maintain a constant 60 frames at all times and some games bring me below that during large scenes. When I make an upgrade which isn't too often I like it to be a considerable boost. And theres a sale right now for 370$ which is 299 euro (think thats the sign you used). Plus a bunch of games that I intend to resell.
