Easily beating out a stock 7970 and the price difference in AU is ridiculous. Save the money and you won't regret it. Buy some games to use that card with with the money saved.
I did it and I am damned glad I made that decision. biggrin.gif
With my OC I can play all the games you mentions on the max setting (Witcher 2 without ubersampling of course) and I have a 1080p monitor as well. thumb.gif

Even BF3? With my OCed 7970 I can't manage a solid 60fps with 4xMSAA. No trouble with 2xMSAA, but it dips at 4x

I haven't clocked that card at all. Though it would be good enough stock.thumb.gif

Then unfortnately looks like you have this problem.
Fault
I suggest immediate RMA, but just to be sure can you touch you card PCB when gaming to see is it temp problem, if you can hold your hand on PCB then temp is not problem, its something else.
EDIT: Now i saw in your rig that you have HD 7970 DCII, but i also heard they too have problems with temps.

This is the only game/bench that doesn't work with 12.4 Beta so I'm wondering what it could be. I highly doubt its a PSU issue and can only assume drivers. CPU/GPU temps are fine and as I said the 7970's were at stock. My CPU is at 4.8GHz but that has been a solid OC for me for weeks. Anyway, I'm going to try a fresh install of Vantage and if that doesn't work I may roll back to vanilla 12.3 and see if that's any better...

Drivers I guess. I have goneback to the drivers released in Jan, they are the only ones which have not given me some sort of problem, and I use 12.3 cap.
Patiently waiting for new drivers and Sapphire trixx new edition.

Both 3DMark 11 and Vantage always do that unless I run them in compatibility mode with visual theme and desktop composition disabled. Or caused by Adobe Flash auto updater.

 

Took me 30 min to figure it out after building new RAID.

My 2500k that I just let go of was 15hr prime stable at 5ghz 1.392v. and my new 2700k can do 5ghz HT on 8hrs prime stable with 1.425v and max boot at 56x 1.575v and posted at 57x, but rebooted at windows logo screen. 1.600v would get in at 5.7ghz for sure thumb.gif

Well you sure seem to have all the luck. My 2600K wouldn't do a stable 5.0GHz at under 1.5V which exceeded my temp limits and my 3960X needs 1.45V for 4.8GHz which pretty much maxes out my H80... frown.gif

LOL, yeah it's either I'm VERY lucky, or just know what I'm doing when I'm overclocking. I have overclocked hundreds of cpus. The one thing that a lot of you guys do wrong is push to much Vcore through your Cpu's and barely use the motherboard. To many try to use the power saving features or the thermal features on the mobo instead of beating the crap out of your phases. If you run your mobo on tprobe (on SB or SB-E) you will end up needing way more Vcore than using Extreme. Yes using Extreme will heat up your phases more and could become unstable, but it's the same as overclocking your cpu, if you push it harder, you have to cool it better.

USE you mobo more and you cpu will need less. Use your mobo less and you'll need to feed more to the cpu. YOU PICK. I know how I do it thumb.gif

How easy is to to OC the 7950 to get it to around the 7970 levels? If I can save $200 for roughly the same perforance I'll be very happy.
Im using a 1080p monitor and will be mainly playing BF3, The Witcher 2, Skyrim and Aliens: colonial Marines when it comes out.
My gut tells me the 7950 is all I really need.
What say you all?

I say RE-take your math classes tongue.gif , $620 - $499 = $121 NOT $220 doh.gif

IF your going to cheat on your tests, make sure your looking at someones answers that are right teaching.gif

Vcore is set to 1250 and memory voltage is still at 1.6. However I'm getting a couple of rare artifacts in long term BF3 play (but nowhere else) so I may need to up one of the two. It has never exceeded 70C though so I'm definitely liking the cooler.

Reference or non-reference design?

This Diamond 7970 is 480 dollars for example.
