Cant you like "buy & try"?
Here in Sweden we always get a 14-day "buy & try", when ordered online. Not happy with the product, return it. Full refund. smile.gif

I would go for the Sapphire, but i understand that you are confused. You hear so many different things about this card.
One is voltage locked, one has high VRM-temperatures and so on...

I can only say, i dont have any issues at all. And it overclocks really well, 1200 / 1600.

I made up my mind an I will buy the Sapphire, but not the Vapor-X.
I found one store that sells the older 11196-16-20G (the infamous 2L) model, which has unlocked voltage and the Dual-X cooler on a reference PCB. I'm sure that will be a nice buy.

I don't wanna risk spending 30e extra on a Vapor-X and then getting a very crappy one. With the 11196-16-20G I know for sure it's a reference PCB and that it's unlocked. tongue.gif.

My 7950 is a Sapphire Dual-X 11196-10-40G. It came with an unlocked BIOS, and the reference 7970 PCB. So far i'm pleased with it, with a factory OC of 950 MHz on the core from a 850 MHz stock (memory is unchanged from 1250 MHz) it has the highest OC of any 7950. I have taken mine to 1200/1550 under water, so i'm happy with it.

That's the one I want, but I can't find it here. So I have to settle for something else.

Avoid the new Gigabytes they are hardware level locked @ 1.25v.
Only older revisions can go up to 1.38V (using Trixx). or 1.30V (using Afterburner).
Gigabyte 7950s most of the time are weak or average overclockers at best. There is a thread in AMD Drivers forum with people posting their Max OC on the Gigabyte HD7950 and it is pretty bad compared to other brands like MSI & Sapphire.

So if I order the Sapphire 7950 Boost (11196-16-20G / 100352-2L) I'll have a decent card for overclocking, right?
I mean there are no locked 11196-16-20G's out there, or has that changed too in the meantime? Any chance of hitting 1200 on this card with the Dual-X cooler??

Did you look at the newest ones at Newegg? They look like reference HD7970 PCB. Not certain.


PCB 109-C38637-00 EK list this number for reference HD7970 nomenclature.

http://www.ekwb.com/shop/EK-IM/EK-IM-3831109856178.pdf

There are two of these cards. Not sure what the difference is other than one of them cost $10 more.

http://www.newegg.com/Product/Product.aspx?Item=N82E16814202030

http://www.newegg.com/Product/Product.aspx?Item=N82E16814202031


Though these cards show the HD7970 PCB nomenclature the photos at Newegg show only 6**6 power connector so the PCB design may not really be a reference HD7970 PCB.

I'm a Greek, born and raised in Amsterdam and currently living in Belgrade... No Newegg for me, hence the limited choice in the title tongue.gif.
