[SOLVED] New HTPC graphics card or new HTPC?

I'd like my HTPC to be able to play 4k HEVC video at 3x speed without pixellating and falling apart (hardware decoder?). I have an open pcie x16 slot. What (if any) are the low power use GPUs with at least 1 hdmi port which will get me there? THANKS!

The GeForce GT 1030 should do the job here.

Your motherboard supports HDMI 4k output at 24hz.
No matter, your cpu alone can not do the job.
Looks like you will need a discrete graphics card to do the job properly.
Here is a good link that explains:

What Is HEVC H.265 Video, and Why Is It So Important for 4K Movies?

4K is the next big thing in TVs, and 4K videos are starting to pop up everywhere.

Low profile might limit you to a GT1030.
Here is a wiki chart with the capabilities of a number of cards:

But, I think the Silverstone grandia series can handle full height graphics cards.
That greatly expands your options.
