Impressive results are impressive, shame about the duff card, just sounds like badly applied TIM. You should ask OcUK if you can re-apply before rma'ing?

I had a GTX 470 that ran hot from brand new, it was fubarred and I ended up RMA'ing it.
I suspect Rusty's HD 7950 may be similar.

Going back to single card so it's going back anyway
How come ? I'm finding crossfire 7950's a huge performance gain over a single 7970 especially at 120Hz. The only downside for me is they are quite noisy.
Not going to notice an extra 7950's worth of performance on a single screen - 120 Hz or not unless you're looking for it with an FPS monitor.
1625. That was a figure plucked from the sky though. Didn't make any effort to reduce it.

Rusty are you going to say anything about microstutter?
If so i believe you need to use the forcerenderahead command and change it from -1 to 1 or 0. 1 wored best for me on xfire. Battlefield 3's default setting has caused microstutter for every xfire user i know.

Very interesting mate, thanks for taking the time and effort.
I completely agree about the surround gaming thing, although some games I can get away with some I just can't. That said I couldn't go back to single or even double monitors for desktop space
Results are making me think even harder about swapping these three incoming 680s for 7970s .........

I notice quite a difference games are a lot smoother especially bf3. With a single 7970 I noticed dips in performance especially in 3d. With the two 7950's it's silky smooth constant.
Wow, I'm hugely impressed/shocked with the results. Shows how the 256-bit bus on the Kepler's really hold it back for high end gaming. Waiting to find out what the big 'but' is though. Hopefully Rusty can test a few more games before sending back his hot card
Sorry I didn't mean I would notice it full stop. I meant I wouldn't notice it for 90% of the time when frames are already decent.
Yeah the rest tonight.

Thanks
Can you comment on the general gaming experience of both setups? Any difference in smoothness, IQ or micro stutter that you noticed? Or do they seem exactly the same except the performance increase?
Will discuss that when I've completed.

Thanks for the time, effort and information Rusty.
I'm not too surprised by the outcome tbh, reviewers should take a good look at themselves and stop taking the cash under the table.
The likes of Kyle etc, that are supposed 'experts' can't give out honest info anymore is poor, very very poor indeed...
'As it is, two GALAXY GTX 660 Ti's together will cost $640 and that buys you a gameplay experience way superior to a highly clocked GTX 680, and competes neck-to-neck with Radeon HD 7950 CrossFireX in framerate and surpasses it in overall gameplay smoothness.'
I mean, two good maxed 680's v oc'ed 7950 CF shouldn't be getting outgunned for the money spent.
I realise there have been big gains from the recent drivers, but I don't think the gains put it out in front that much.
I'm guessing the 'but' will contain some jumping through hoops trying to apply voltage to the second gpu, it happened at the beginning of the 69's life, but was sorted soon after(for me anyway).
Shouldn't have happened with the 7 series, it should have been simple as ticking the box from the very start, this is where AMD shoot themselves in the foot.

Still nothing on the bios modding psy with the 7's, I don't even know if it will come either due to the way the tech works in regards to determine the different stock voltage between cores.
The AMD rep/tech over in another forum, said he couldn't go into detail about the new tech used as it was hush hush, but I reckon that's the stumbling block with bios flashing.
Set the voltage in RBE, unlocked CCC limits with reg files made 2 profiles in CCC and away I went with my 69's, it was so so easy, you didn't need anything else.

They all have a dual-BIOS so I presume you can flash it to one of them. The first BIOS is locked so the 2nd one is for messing around.

Exactly Tommy - it's ridiculous.
I know that there are always going to be slight variations in results but the fact the 7950 is so much faster at triple screen resolution in BF3 is astounding for how much they cost. The cards aren't even in the same point hierarchically! And you have to bear in mind as well that my 680's were quite golden clockers and my 7950's are average (well one of them are).
To be fair I'm not sure they reviewed triple screen resolution and crossfire of anything above 7850/660 is always going to be slight overkill for a single screen anyway. The fact that reviewers try to say otherwise though without testing it properly is ridiculous.
I have no bias - I wouldn't have sold my 680's for 7950's otherwise - shame on all the people who thought I was a nVidia "fanboy" - (yuck at the word!) so my results may not be scientifically perfect they are what I believe to be reliable.
I have to state it again - I've got a knackered card as well. With a card identical to my first one I could easily push 1200+ on the core and be under 80c which would be my comfortable limit on these cards. The difference would be even more profound.
Anyway it's not all good news but on paper at least it's large.
My "but" isn't a deal breaker and it is somewhat subjective so it'll be up to people to decide individually. If I was staying triple screen, I would be keeping the 7950's (well keeping the one that works and getting another!) so based on that you can assume it's not a terrible thing.
