No rush. I don't think anyone here plans to buy one. We will just use the review as evidence that Nvidia is fleecing people at those price points.
Honestly the 950 pisses me off. On any other product cycle for Nvidia right now in September should be when we get the sub-$100 cards with that HEVC decoder. But here we are and the only cheaper option that has it is a 950! ARG!
Where is the 940 (aka the 750 replacement but with the nice HEVC decoder)? Does HEVC decoding need X amount of shaders to do the job, or is Nvidia just milking the HTPC market for all it is worth? If it is the former, will we not see that HEVC decoder in a sub-$100 part until something at a 950 level is on sale for under $100?
Those are the questions I want answered. We already know what a waste the 950 is.
Nvidia has been mixing up model numbers in their product cycles. Put too much weight on the name and it doesn't make sense. ie, the conventional 7xx line is mostly rebrands of 6xx parts. The 660 in particular was continuously sold until the 960 came out, because it filled a lower power segment that the 760 didn't address (660 would work in single 6-pin < 150W capacities).
In that same vein, the 740 / 750 / 750Ti are not 'last gen' cards, they're the first Maxwells and as such I don't think you will see them directly replaced by another Maxwell. The analogy is in the same way the 7xx line never directly replaced the 660.
Basically Nvidia's current 'modern' lineup is :
740 / 750 / 750 Ti (Maxwell v1)
950 / 960 (Maxwell V2.1, smaller v2 + HEVC)
970 / 980 (Maxwell v2)
980 Ti / Titan (Maxwell v2, just bigger)
I doubt we'll get any more Maxwell chips, though we might see an overclocked version of one of the above with a "Ti" tacked on the end of the name.
I think your best hope is to wait for the 950 to come down in price, probably in a couple of months, assuming it's worth the wait for you. Otherwise, just get one. Personally if it were me, and that filled the bill of what I needed, I wouldn't spend time waiting / watching to save $20-30.
