It depends how many screens he was using, what programs were running. For example, I run three screens on three GPUs. One sits at 500MHz, the other two at 250MHz. But when playing a video/youtube/Veetle, they jump between 250MHz and 880MHz (top end).

So can a 7950 max BF3 all bells and whistles at 1920x1200 and produce playable frame rates?
Soldato
Does that at 2560x1440 so i'd think so
Granted at this res i have no need for AA as it gives no visible improvement.

Heaven benchmark, stock clocks on the left, 1ghz overclock on core on the right.
Max temps are 78c according to MSI AfterBurner
Very good considering my case (Lian Li V354B) has a crap airflow around the GPU with a sound card directly under it.
EDIT: Just realised the GPU-Z screenshot says PCI-E 1.1. That's normal on idle. When on load it jumps back to 2.0.

What temperatures is everyone seeing on their cards and with which coolers?
I'm quite impressed with the Powercolour PCS+ cooler, max temperature i've seen out of it is 65/66C with the furmark burn in test running and at that temp it's only a 50% fan speed.

I've been tempted by the Powercolour too but I'd like to know how much louder/quieter they are to reference design, moreso the triple 80mm-fan Gigabyte WindForce OC. They've attained the high clocks with good sound levels, essential for 2/3 GPU [source]
The 7950 range is far more impressive with non-reference coolers compared to the 7970 range which seems to have only the XFX Double DD B.E. More on the 7970 DD cooling in this review where idle stock clocks are 9c lower than Sapphires. I thought all 7970s exhausted hot air out the case (reference designs do) but this one circulates it in the case! As appealing as some of those temps/noise-levels may be, your paying £170 more for a single XFX DD 7970 (£1120 CF total) compared to the XFX DD 7950 (£780 CF total). The £340 difference would just about get you another 7950

I have an Asus CuCore 7950 and in furmark, stock voltages @ 1050mhz max temp = 68C with 32% fan speed.
Yeah, I'm happy with it

I've just been comparing my xfire 5850 set up with the results that Gibbo posted and looking at them, I can only see the extra VRAM being worth the swap atm.
Is anyone here with a 7950 (and unlocked bios with high clocks) able to do some Unigine runs with higher settings, like 8xAA and 16xAF, to see how much the 7950 might pull away?
7950 max clocks
5850 xfire 950core/1100mem
580 max clocks
Edit; here's my results from 16xAF and 8xAA

7959 PCS+ is impressive.
Default voltage was quite low at 1031mv and Heaven crashed when I started to increase the clocks.
Used 1093mv and tried 1000/1400 which was fine seeing 61 degrees C @ 41% fan speed (room temperature is not exactly hot though).
Those 92mm fans do a good job.
Will see what more it can do when I have more time as I had to fit in a little bit of BF3 for test purposes (that's what I told wifey anyway).

Something quite wrong with your 580GTX overclock if thats what it gets at its max seen as my single GPU bench at stock is 1360~ lol.
at that res?

You can have glitter if you like...
Can we?
Yeah, but it'll cost you !
How much?
Pound..
Haha very funny ....love that film.

Speak to Gibbo, it's his bench result from the first page. Why don't you post the result so we can quiz him about it, rather than making a silly flippant statement about it.
Soldato
How about you calm down and post the clock rates actually used. Nothing flippant about that post at all. Just an observation.
I think what's being queried is that is your score at 1920x1080 with 4xAA or perhaps at 1680x1050 with 4xAA as per the Heaven benchmark thread?

Cheers for the info that takes out any guesswork.
Yes I'm liking it already, barely audible at idle (the sound I do hear might actually be my Vantage cooler) and not much more sound under load'.
Please could you share the link for the Asus OC bios or the one you used? The one that I used flashed ok but I just get a black screen after the windows logo so I re-flashed to original.
Thank you
**Edit
Sorted it now, I used this bios which is different than the one posted earlier in the thread:- http://www.techpowerup.com/vgabios/113028/Asus.HD7970.3072.111220.html

How does that BIOS differ?
