ATI 6970 upgrade
 

Right now I've got the following:

Win7 64
Asus P6T Deluxe
Ci7 920
3Gb RAM (PC3 10666)
ATI 4870 (1GB)

I built this ~2.5 years ago and it's owned everything, till now.

I'm looking hard at a 6970, specifically this

If I dropped this into my rig, what should I expect? How about the RAM?

ATI 69** has a visual bug in this game since day 1. Have to advise to go for gtx580.

I have a 6970 and think it's a great card, but I would not recommend it for CloD because of the horizon graphics problems that the devs don't seem interested in fixing (blue lines and mishandled horizon haze). Get a GTX570 or 580 instead.

I'm aware of the 3 lines issue. I wasn't motivated to buy today. Figured it'd be fixed.

But I'm not married to ATI either. Is there a comparable gx580? What was attractive to me about this card in particular was the heat pipe design. (low noise)

Also, I guess I should get a 6Gb kit too. Is it worth it to get the higher memory frequency ($$$) or just get some low latency (PC3 10666)?

I have 2 of those Powercolor cards in crossfire. I can tell you that one will run a single 25 inch monitor at good speeds, 80 to 100 fps with everything on high except that SSAO is off, provided the rest of the system is up to par. It also runs substantially cooler than the reference design card, despite the fact that it has a decent factory overclock.

I got a second card to run triple monitors better, and it does pretty well, though not what I'd hoped. Also, in crossfire the airflow to the top card is largely blocked by the bottom card, so the top card runs on the warm side now...

In general higher clocked or low latency RAM does very little for performance in games these days, especially when coupled with new CPU's
At most i'd get a CL9 1600MHZ set as past that prices skyrocket for barely any gains.

As for the 6970, my system with a 6950 runs CLOD very well at high settings and besides the blue lines issue, which will be fixed sooner or later, has no ATI specific hickups at all

This is noted in luthiers latest post as bug to be fixed.

Iºm running two hd6970´s in crossfire and after the latest patches it runs silky smooth with everything maxed out. Noise and temps stay nice and low too.

Blue stripes bug is an immersion killer but Luthier latest notes give hope that this annoying bug will be fixed soon.

Sorry to trail offtopic but I think the issue Luthier describes as "landscape stripes bug" are the stripes of water ,or stripes of land, that appear in places they don't belong.
I've seen it mentioned in several threads that the horizon stripes will be fixed based on that line ,but the wording makes me think he's talking about actual landscape and not the horizon.

I unfortunately think you are correct, but am hoping not :)

sooner or later it will be fixed
And this is taking from the: Next patch info: Finally fixed the landscape stripes bug:grin:

I am afraid the key word is "landscape".

I've my doubts too, because else they would have used the word "horizon" instead of "landscape". It looks like the blue stripes belong to the ATI driver department because the blue lines only appear with 69xx cards. But it looks that ATI doesn't give home and thinks that their customers can't install their drivers properly. I hate it that ATI doesn't take its customers serious so far. I hope they will change their attitude toward this problem and its customers. Next time I serious consider buying Nvidia although the 6970 is serious bang for the buck.

I purchased the card and the ram

My new specs:
Win7 64
Ci7 920
Asus P6T Deluxe
HD6970
6Gb (3x2Gb) PC3 10666

Everything is stock except for the video that comes slightly OC'd (940MHz)

I now run the game @ 1680x1050
All graphic settings are on except
AA:2x
Epilepsy = off
SSAO= off (what is this?, should I turn it on?)
Vsync = off (works well, everywhere but London)
Buildings amount = High
Forests = Medium
I get 32fps adv on the black death.
Rooftop level in London will average 20-30 w/ dips in the teens that exhibit some stutter. (less stutter than I got @ 60fps when I had 3Gb RAM)

Otherwise the game is jaw-dropping-gorgeous and I stay in the 60-100 fps range most of the time. Yes, I get the horizontal blue lines; I've emailed AMD. Needless to say that all my other games are much improved. Essp. Dragon Age 2 (Dx11)

I would recommend this card.
