Doesn't TAA, which most games use nowadays, require data from the previous frame, which makes AFR impossible (most SLI profiles mainly use variations of AFR right)? I remember listening to Nvidia about how many modern high-end affects require inter-frame dependencies to function correctly, and for performance, which makes traditional SLI methods harder and harder to implement, or get large performance gains from (I assume this is way they limited it to 2 cards).
Does the rendering engine being forward or deferred have an impact on potential SLI performance as well?
Anyway, though I don't have a 4K monitor, I love downsampling from 4K as the image quality is beautifully pristine. I generally found that 1.7 resolution scale usually delivers extremely nice downsampling results without being as performance demolishing as 4K. My GTX1080 is more than good enough for me right now.
Seeing the new pricing structure for these cards though makes me think that the Ti cards will be the only way to go going forward, as long as they aren't selling for over $900.
