Can a 7950 Overclocked offer near 680 performance for less money.

I'd hope it's a bit more than that.
Scaling with the 79XX OC'ing is quite good, a 40% OC equates to quite a boost.
At a 40% OC, the 7950 is faster than the GTX680.
Caporegime
i think a pair of xfired 7850's would be more interesting compared to single gtx 680,works out cheaper too
i guess overclocking is all about luck.
But have you checked that your voltage isn't actually set lower than the standard reference voltage ?
Caporegime
Price/Performance the 7950 is a great card. If you prefer Team Red, then go for it.
Caporegime
I am not disagreeing with you but is a 1295mhz clock a reality for a 7970 or 1260 on a 7950?
Caporegime
A 40% OC on a 7950 is 1125MHZ, from a stock of 800MHZ.
I never mentioned anything about OC'ing a a 7970, other than the scaling is good.

lol I just took the top card from OcUK and see it was 900. I didn't look at anymore (too lazy me). As I said, I wasn't disagreeing with you just asking.
As you put 79XX, I took it as both.
Looking at the Heaven 3.0 benches, my OCed 7950's are in spitting distance of OCed SLI 680's so I would say yes, they can get close.
But only when OCed will a 7950 get close, and not all 7950's oc the same. My second card I can only get around 1070 on, and no amount of volts will get it higher.
First card I can easily get up to 1150 on.

i'm not sure about that, the dual cpu cards are sold for their bragging rites only, it's simply to say ``we have the fastest card`` as such the prices stay high...... a bit like a Rolls Royce, one just has to accept this.
the mid range high performance cards...... yes you're right

pricing is always an absolute joke on these sorts of cards. the problem is though, people pay it and that is why nothing ever changes. can't believe there are some who use things like dual 6990 and what not, what is the justification for doing so, because for gaming there is no point unless you are gaming at an insane high resolution. hell me 4870X2 is still handling most things without too much trouble and its three generations old, its like an antique.
so for a question, what do you crossfire 7950, 6990 users actually do that warrants so much graphics horsepower, same applies to the 580 switching to 680 bunch, what is the purpose of switching when most of the time the difference will probably be not obvious the majority of the time? too put it into perspective I want to get rid of my 4870X2 because it doesn't support Direct X 11, it consumes tons of power, gets rather hot and sounds like a leaf blower, which I would like to think is a reasonable point for changing. also its not like an 'attack' or anything, just an honest question?

Apart from the clocks that can indeed easily be increased to 7970 stock levels (925/1375), one should also take into consideration the noise increase. The load noise is considerably higher with 1000/1375 and voltage increase compared to stock...
I have a Sapphire 7950

Do you understand the logistics of putting two GPUs on one card Mal?
It means double everything. Double the GPUs, double the transistors, double the coolers double the connectors.
That is why they cost what they do. It's not possible to just throw two GPU cores on one card and use the same parts and prices that you used on a single card.
Not only that but they do not sell en mass. This means that you have to bring in a designer to design and create the PCB and all the other bespoke stuff (like the two slightly smaller cooler blocks) and the shroud and so on. Then you need to commission a company to actually manufacture them which comes at a cost.
Now obviously if I were to go to a company that manufacture heat sinks for example (vapour chambers) then costs would be dramatically lower if I were to ask for 50,000 and not 10,000 as an example.
Like everything in life that you can buy the price is easily understood when you understand just what goes into R&D, manufacturing run costs and so on.
This is why cards like the Asus Ares and MARS II cost what they do. Why? because every single last part on them apart from the memory (even though it's double that of a normal card) and the GPU itself are completely ground up customs. They only make 1000 which means they don't get a bargain by going mass production, and all of those costs are passed onto you.
It's kind of like buying a standard Range Rover. It costs a set price. However, taking it to some one like West Coast Customs and asking them to make it completely unique will come at a cost.
Dual GPU cards are not cheap to make. They are not cheap to design, and they don't sell in mass numbers. Because of that you pay the price for them.
can a custom fan profile in trixx sovle that though, my unlocked sapphire 6950 runs hot even when standard but I worked out a custom fan profile to sort out my 950 1400 overclock. I agree noise is def a factor as long as its tolerable.
If same clocks, 2-5% difference same as the 7970.
so, overclocking the 7950 is a price/performance king.

Except it's not.
Two 6950's in 2010 OC'ed and unlocked to 6970's were much better since they offered more performance, sameish price, almost 2 years ago.
