Do those even allow GPU installation?
The strict answer is "yes." But, I tried running a GTX 1070 in an old Atom-based board with 8-cores and a clock speed of something like 2.0Ghz, and the system could barely run YouTube videos. League of Legends ran at like 10-20 fps--was unplayable. Don't think I tried running any other games.
That these support a modern iGPU (rather than one that uses VGA exclusively) leaves some hope that these CPUs might be able to square up against fairly modern titles. Maybe not on the integrated graphics, but their presence and the HDMI port are reassuring.
I really like that this board appears to support desktop-sized RAM, these might actually be a value-oriented choice for a HTPC-type machine. Granted, they are now competing with Raven Ridge and a budget AM4 board.
