I'm considering getting a new desktop PC. It'll be more or less based on the one mentioned in the "cheap" barebone.

My current desktop has only 8GB and doesn't support any more even though the CPU is up to most tasks (i7-2600). It has a Nvidia GTX 750Ti and handles Qubes okay by default (on its own SSD) although 8GB is very tight.
I also have another SSD with Win 7 on it for games only.
While this setup works, 8Gb isn't enough for what I'd like to do. So now I'm considering a replacement.

My desired specs would be:
- Z170 motherboard with support for up to 64GB RAM (future proofing)
- i7-6700 or maybe even i7-7700 (is it supported yet?)
- Intel HD graphic from CPU
- M.2 SSD for Qubes + SATA SSD for (HVM) Windows (games only)
- 32GB of RAM
- A/dual GPU, but which? AMD seems most likely (see below)

I'd like to be able to play some games on it, so I'll need a GPU and thus the choice ends up between Nvidia or AMD. My thinking is that if the Intel HD graphics is used by Qubes on one screen, the additional GPU could be dedicated to a HVM and perhaps even play games on it on another screen (in the future, for now rebooting suffices).

I've been digging through the posts and seen lots of issues getting NVidia to work with Qubes, although Qubes didn't need any additional configuring for my current NVidia card. But since I have only one GPU I can not test HVM graphics separation. I haven't found any posts about AMD GPUs, however, I did see on the Xen website that secondary ATI/AMD GPU passthrough is possible, depending the hardware.
(Source: https://wiki.xen.org/wiki/Secondary_GPU_Passthrough )
I know that page does say Nvidia will only work with certain patches and certain Windows versions, so that route is turning into a no-go.

Ideally I'd be able to use Qubes and be able to play Windows based games without having to resort to dual boot. (Kind of like in the Ubisoft demo of 2011: https://www.youtube.com/watch?v=Gtmwnx-k2qg )

Is this possible? Can it be done with Qubes or do I need to "build" my own Qubes variation on Xen?

If this isn't possible, I probably end up getting a PC for the games albeit lower specs and a separate laptop for Qubes.

Any thoughts or recommendations are highly appreciated,
