Or would it be significantly better than other SLI/crossfire solutions due to it being so good in the first place?
I am working my ass off in order to get another TITAN in but I haven't had any luck yet. NVIDIA sent out all their TITANs with the prebuilt systems to reviewers. I asked for the SFF chassis which means I ended up getting only one. Even ASUS and EVGA are pretty much coming up dry these days.
If I had to make a prediction, it would be that two TITANs in SLI would exhibit the same issues as two lesser cards. HOWEVER, the actual visual effect would be minimized since extremely high framerates would be achieved (and thus lower overall frametimes) but there would still be some issues in the games I mentioned in the review.
With a TITAN SLI setup am most interested in the large buffer's effect on those large 70ms++ hesitations SLI exhibited in Hitman and some other titles. It could very well be they are due to the memory buffer being unable to keep up with certain processing requests, which means the TITAN should minimize them due to its massive 6GB of memory.

I have also seen some people report better (smother) gameplay in some titles with HT enabled. Doesn't seem to be ant rhyme or reason for it. No one seems to be able to tell for sure what the problem is, just that it's there with some titles and not others.
I have no idea why AMD's solutions stutter so much. I've heard some back-room buzz that there's communication issues between their primary processing stages and the memory controller but those are simply rumors right now.
With that being said, I have indeed encountered higher instances of stuttering on AMD systems but there's just no way to tell whether that was due to the lower starting framerates or something else.
That brings up an interesting test though: on an AMD vs Intel basis, with framerates being equal, which will display higher frame times? Looks like my next article has been decided....
