So you have a 2560x1440 laptop with 680M SLI now? I clearly show Titan being 2x faster than GTX670 in Company of Heroes 2. That alone disproves that 680M SLI can beat Titan in "every game" because you'd need to overclock the memory on 680M 65% to get to 670's memory bandwidth and the GPU clock almost 40%. You expect people on this forum to believe you had oveclocked 2x 680M 40% on the core and 65% on the memory on air in a laptop, and the CPU was also overclocked? Was your laptop dipped in liquid nitrogen? And that's only enough to match a stock Titan in CoH2. In some games where Titan excels, the 680M loses by 15-30% to a 7970M for crying out loud. HD7970M is slower than a 7870. You expect people to ignore those tests too?
My guess is you are comparing 680M SLi on a
1080P laptop against Titan on a 2560x1440 monitor. In that case sure the 680M SLI OC on your previous laptop is faster than Titan on a 1440P desktop monitor. Such a comparison is completely misleading however and is not how Adam was comparing the 2 setups.
You seem to also be ignoring that 680M has a voodoo power rating from games in reviews. 670 is 50% faster than 680M and in some games it takes 670SLI to match a stock Titan. Please explain to everyone here how your 680M could overcome a 50% performance deficit against a desktop 670 in the first place? Or you are just going to keep telling us you tested games and we are expected to believe that?
