i think i would care about temperatures as i would want the card to last a while if im going to invest that much ca$h into it
True, but if you put them in CFX due to temps (air cooling) I wouldn't be surprised if the Lightnings clock a bit better. Single card... well maybe the DirectCU has the slight edge.

Thread Starter 
I am happy that msi listened to all of us to put some sinks on the vrm and mem, BUT (though am nit-picking) it would have been much better if its not just a plate. I mean if it was a zig-zag thingie more surface area, but hey this thing is not meant for air .

I just hope they release some dual gpu cards with lightning features on them. A 6990/590 make them triple slot with 4 fans, 5 heatpipes connected to 1st gpu cooled by two fans, then another 5 heatpipes connected to the 2nd gpu overlapping the first two fans, and again another 2 fans on top. And all the vrms u could put. The card will weigh about 2kg and cost 1000+, but hey ...

Nah, more like a 570.

BC2:



2650X1600 and below, get the 6970 only when running in Xfire, but they have some strange problems with 5760x1080:

^ Why do you keep reusing those same graphs? If you use Crysis, 6970 will then beat a 570. It depends upon which games you play.

Crysis Warhead you mean. No one actually plays that anymore, it's a benchmark, just like Unigine, 3DMark and Vantage(which the 6970 loses in, yet means nothing in real world gaming though).
Every other "game" has problems at 5760x1080 with ATI. Hopefully they'll fix it? Most people don't have triple monitors though so the 6970 is a better choice at 2560x1600 and below if you're running CFX since you can crank the AA up if you want. They do poorly in single configurations though. Even a 560 beats it...

But if you want a M-GPU the 570 still does fine even with its limited memory.

I say the Guru3D review seems to support that in most games. At least for this model.

The thing is those graphs the 6970 CFX is only at 929MHz. The TFIII will go much farther 929MHz as I have already seen two reviews over 1000MHz. Finally, the 570 at 940MHz is 1) VERY good chip (the average one does 900MHz) and 2) you risk the card when you overvolt it.

The reason why those reviews are bunk is not everybody gets TWO 570s that clock that well ... where the 6970 TFIII is binned and will beat the vanilla 6970s at 929Mhz you proudly post in every thread.

a nice looking card. 2x8pins are too much though (for me at least).

The 6990 is at 940. Here's a 6970 at 1021Mhz:



1021Mhz 6970 81 fps @ 1920 = 3 fps gain from extre 80Mhz OC vs 101 fps from 570 at 940Mhz
1021Mhz 6970 62 fps @ 2650 = 1 fps gain from extra 80Mhz OC vs 77 fps from 570 at 940Mhz

1) 1021Mhz didn't change much at all... 1 fps...
2) Both my Asus DCII 570s hit 1020Mhz with 1.17V and cost less than this 6970 TFIII. 1000+Mhz can be obtained by every DCII 570.

lol... Stock comparison... This is OCN, not stockclock.net

I'll restate my conclusion again: Most people don't have triple monitors though so the 6970 is a better choice at 2560x1600 and below if you're running CFX since you can crank the AA up if you want. They do poorly in single configurations though. Even a 560 beats it...

Look, I don't understand why the 6970s do so poorly at 5760x1080 in BC2, HAWX 2, Mafia II and Lost Planet 2 either. They should actually be coming out on top since they have more frame buffer and scale so well that they're equal to two 570s at 1920 and 2560. Maybe a simple CAP update will fix this? Maybe the Xfire bottleneck is coming into play here?
