thanks for your replys. Will it really be as expensive i thought it would be the price of the gtx 680m now then they would just drop the price of the 680m. Do you guys think the performance increase will be over 20%
Just to clarify, as of now the 680m is a very mature card that thanks to perfected drivers and modded vbios has reached its full potential (can be overclock up to 1040Mhz core clock and 1100Mhz memory without big temperature increase). The 680m SLI allows its owner to play several highly demanding games (Far Cry 3, Crysis 3, Metro LL, Batman series in DX11 and many others) maxed out. The 780m is still a young card that will need considerable time and tweaking before it will reach such potential. Have no doubt, as of now 680 SLI is more performing than 780 SLI. Sure, in a few months we most likely see the 780m unleashed, after the usual gurus will mod its vbios and remove all the limits nvida embeds in its mobile cards. Now the 680 SLI is still a most performing and outstanding graphic solution.
