AMD CPUs are fine, a lot of us use them.
16GB of (I assume) system RAM is mean but not unworkable, I believe. In general you would want more, and you want two to three times as much system RAM as GPU memory to allow working space (and ideally more than 8GB of GPU memory). Currently 10x0 and later nVidia cards are supported, but the 10x0 cards are deprecated - menaing they could be dropped at any time.As you say, Iray can remnder using the CPU, but it is much slower than almost any GPU - I suppose any kind of heavy load does increase wear and tear, but if you are concerned you can use the Affinity section of the hardware tab of Render Settings to limit the number of cores that will be used (which obviously makes the render slower). If this is a desktop system you should be able to swap the GPU, but bear in mind the advice about system memory in proportion to GPU memory; if system memory runs out the data should be swapped to disc, but that will make the process much slower 9and if the temp file is on a smaller SSD it may run out of space, and will suffer wear from frequent writes).
The other two features of DS (main application, currently) that will use the GPU use different features and are not tied to nVdia cards (though AMD does seem to be at least sometimes problematic with OpenCL, used by dForce, as it supports a later version of the API and doesn't always work well with the version DS wants 9nVidia and intel GPUs dop work, as does the Intel OpenCL driver for CPUs - which, I beleive, also works for AMD CPUs)
Recebtly nVidia seems to have dropped an older gernation from Iray support about the time a new geenration releases. That isn't guaranteed, but going by recent patterns the 30x0 cards would be supported uintil after the 70x0 cards arrived and the 40x0 cards until after the 80x0 carfs arrived, so yes it would seem likely they would be supported for a while yet.
Daz is developing Daz Studio. Iray is licensed from Nvidia.
When a card is no longer supported, it means that at some point in time NVidia will release a version of Iray will not be able to be used by certain cards, and when Daz implement that version, the users cannot render with these cards.
