very slim. probably not at all. I can say 99% sure that the 880m won't make it in as the 780m is actually better than it at many tasks since it is just a rebranded 780m with more ram. Many programs don't utilize the 880m's ram and even where it is faster in terms of FPS it is only by a few tenths per second. I still have the chance to return mine but if it is for the 880m I am not sure it would even be worth putting it all back in the box
Well I hope that doesn't stop them from going with the 850m/860m in the base models. I have no interest in the higher-end cards... you're absolutely right about them.
