Hi, Well I actually got a Clevo P370SM with a sli of 780m, and I must say that reaching 9800 on 3d marks for the Fire Strike test, it is just freaking amazing. This combinaison is better than a single titan card at stock, and it runs every single game around at max out setting 1080p, and probably even higher if you turn off AA on a 2k screen. I don't even mention the incredible OC you can do with it, which is quite amazing. The 880m is honestly useless, the temp are getting way to high, and the OC is clearly limited by that and the chip itself. So right now, I would definetly advise to buy a sli of 780m, it's not too expensive, and it's very future proof. The 900 serie is probably going to be very expensive, so now it's the time. ^^
