860M SLI (x2) vs 880m

[AbstractAIz]

Which is better a 860M SLI (x2) or a single 880M in Gaming Laptops. Please don't answer this question theoretically {cores, speeds in every GPU} or at least don't base your solution in it. I need to know the FPS and benchmarks on low and high settings of the latest games (especially First Person Shooters such as Ghost, BF4 etc...)

If possible, provide evidence and sites showing these results

I want to know the answer to this question as well. I can either get the Alienware 17 with 880m or the Alienware 18 with 860m SLI for the same exact price. I haven't seen one set of benchmarks so far testing out the results of 860m in SLI, and in general I've never owned an SLI machine before.

I would assume that sli 860m is better 880m. Reason being sli 770m slightly outperforms 880m and 860m is better than 770m.

860M SLI would give good results in benchmarks only, not in games. 860M SLI in games should give a performance similar or slightly below 780m. SLI performance is never 100% increase from a single GPU, some games will give 0% increase while other would give 90% increase at most. So it is safe to assume 50% average. This would greatly depend on the driver and 860m is SLOWER than 770m not faster.

The link above should provide the exact details.

Well… A 880m is much better than a 860m SLI, because not all the games support SLI and dont forget that the dual 860m wont be 100% efficient… so a 880m will still beat a dual 860m in some cases. For more info, visit this site: http://www.notebookcheck.net/NVIDIA-GeForce-GTX-860M-SLI.118589.0.html
