What happen to those EVGA 6GB 780Ti's that were supposed to be coming?  Looks like the timing to pick up a pair of those bad boys may be in sync when P3D2.3 drops. 

 

 

As it stands now SGSS AA can take as much as a 50%-60% or more performance hit at 2560 x 1600 (even worse with many cloud layers)

 

Interesting.  I am only running 1920x1200, so w/ AA setting of SUPERVCAA_64x_4x with 2xSGSS, and MSAA 4x in sim, and 16xAF in NI, I get virtually no detectable hit over plain MSAA 4x in sim.  Moreover, if AA is altered appreciably by LM and/or Nvidia to work better in P3D it's really hard to say now if that automatically implies more processing overhead on the GPU.  It may just be that different AA algorithms will work better and not necessarily imply more impact to the GPU, in fact the hit might be less who knows.   So for my situation, I think the argument holds up well.  I can see cloud shadowing being improved w/ SLI even in my rig since it's typically only then that I see GPU utilization hitting a wall, but w/ the cost of a 2nd Titan I'd have to see cloud shadow performance improve dramatically.  There's also that hard quantify effect that SLI may end up leading to smoother video which could be useful, though GSYNC may be more useful in some ways perhaps.  Yes, wait n see's the word!
