This thread has been quite informative! My assumption is dom0 having access to an iGPU wouldn’t improve system performance that much. I don’t plan to use dom0 for anything other than system administration. So all the apps that would benefit from a GPU are in VMs.
One option is to concentrate all graphics heavy applications into one VM that gets GPU access. Given how I want to separate my VMs, this isn’t that great of an option for me. The other option is to minimize iGPU spend, and just know some programs will run slow.
I like Novacustom in general, but I worry about Intel chips these days. I was thinking of picking up a new AMD based system instead. The rumor is their 395 Max chip will come out early 2025 (strong iGPU), along with their new X3D laptop chips (essentially no iGPU, but with extra cache). Given that I don’t want to switch which VM has access to a GPU all the time, I might just go with the X3D option. This is of course if I can find a manufacturer that sells it without a dedicated GPU (or with a removable GPU that I could sell to reduce the total laptop cost anyways). I guess it also depends on CPU core count for the X3D chips. If it’s comparable to the 395 Max, then that makes the decision pretty easy.
As an aside, I’m aware Qubes might not work on new hardware right when it comes out. But I’m confident it will work eventually. And I might be able to make a contribution to the hardware compatibility chart this way.
