So, all-in-all, a 60% jump over the 680, but also behind the, still, best-of-the-NVIDIA-best GTX 690.

The prospect of tri SLI for these cards makes these more appealing to me than a 690. By itself 690 isn't enough to drive 3 screens. It's no secret that 690 quad SLI doesn't scale well but tri SLI witht hese cards apears to give very impressive scaling. With these cards in tri SLI, 3D vision surround @60 fps per eye or 120 fps surround may be possible...

?I'd estimate quad doesn't scale because of CPU bottlenecks, not GPU's fault really - I'm running three 3gb GTX580's in tri-SLI and for quite a lot of stuff, games were faster with only two cards, because the added cpu cycles of running a third card impacts the cpu enough to cause the speed to actually drop below that of the GTX580 in situations where the GPU's were running at the maximum capacity of the supporting CPU.

ive been posting on nvidias forums for 5 years now and quad gpu has never scaled well and not because of a cpu bottleneck. its fine for synthetic benchmarks but drivers dont work properly for most games. check out some quad benchmarks on the net. some games have lower frame rates for quad sli vs 2 way sli.

The problem with that is when someone does quad SLI, they do it with high end cards, or at least pretty-damn-good ones, so the difference between performance gain from 2-way to 3-way or 4-way is much less than the jump from single to 2-way, CPU bottlenecking will always be a contributing factor, as the more GPU's you add the higher the load on the CPU just to run them, more cycles needed to support the GPUs means cpu runs slower for everything else (the game), impacting the performance - that is why synthetic benchmarks that measure the GPU alone show much better results than 'real-world' games.

im talking about multi screen gaming as that is the only use case i see tri or quad sli being useful for. i agree that cpu will hold you back on a single monitor but thats well in to 100+ fps. However when pushing 3x1080p youll be struggling to do 60 fps with quad sli anything... best bet before the titan was tri 680 sli which barely plays bf3 maxed out on 3 monitors at 60fps(4 gb models).
