After reading this, I feel relieved that I stretched for a GTX970. I suspect that a 960Ti will turn out to be what I hoped this card would be, but right now I'd probably be a little irritated if I'd waited for this.
I have to wonder though, if its performance in SLI would be a redeeming feature, although limitations on amount and bandwidth of memory may hurt there too.
I will agree with those who are looking at the potential of that single-fan Gigabyte model in a mini-ITX rig. It seems to me that single-fan coolers ought to be a lot more common on cards only needing a single 6-pin PCIe connector; additional fans and huge heat sinks appear to add a lot of cost, but not much benefit except perhaps a few dbA of noise reduction. As much as I like quiet, I don't think it is worth it.
