GTX 670M SLI vs. single 7970M

Hello

I am looking into buying a Schenker from mysn.de and they are currently offering a graphics solution with two GTX670 in SLI configuration. The price of this and some other upgrades I would choose are well under the price of the 7970 setup I was thinking about buying.

Does anyone know what kind of performance that would be expected from these two setups? I know the SLI setup in desktop cards is way more powerful, but the desktop and laptop cards can hardly be compared.

I am also aware that I have not posted other specs for the system I am looking into, but I don't consider these important as I am pretty much only concerned about the gfx.

Thanks!

By the way - am I posting in the correct forum? I think the Schenker is a Clevo or Sager, but I am not sure.

 

7970 should outperform it, however enduro is currently crippling the card. dual card setups have additional complications with them because some games dont use SLI as effectively as other, you run into microstutter, etc. Dual card laptops are also huge, have gigantic power bricks, and are significantly less portable. personally if i were going for a laptop id go with a single card solution for the sheer sake of mobility.

 

Yes thats the correct forum.
It depends which laptop you choose. If it supports switchable graphics (the integrated + dedicated) you are better off using the 670M in SLi. If not, go for the 7970M since then it would not be crippled by Enduro.
But of course you need to keep the driver issues in mind that AMD GPU's suffer from. Nvidia generally has fewer driver issues, but are more expensive.

 

While the SLi setup will run into multi card issues which adds to its driver troubles.
