Hi,I tried to find a video explaining all about what hardware you should focus on for Daz Studio (which is what I use) but I think this is the channel where you can find answers to all you questions:

I myself had sourced a third-party who builds custom PC's and all I told them was my budget and that the GPU has to be Nvidia (I don't recommend any other GPU maker if you plan on using Daz Studio as well)
Cheers
