The features are what make it "streamer friendly"
For instance, 23 USB ports and more headers!!! I can't even imagine what it would take to fill 23 ports.
Love the purple as well. Sucks the AMD board is orange. Can't think of anything that would go with it as is.
That's a good question, to which I actually have an answer to, maybe
VR Streaming (even non-Proffs).
The Index I have, with only 3 body tracking points, is 4 (6 if you wire the controllers, which you can) USB ports and each extra body tracking point adds one USB. The ideal is 10 point body tracking (2 hands [you can track hands independently to controllers], 2 elbows, waist, chest, 2 knees and 2 ankles/feet), so that puts you at 12 USB ports just using a full body VR experience. Then you have all the stuff to power the cameras and stuff. Depending on how you set the scenes, you can have about 3 cameras? That's 3 more USB, so 15. Then you have whatever other stuff, like microphone or external DAC / sound, keyboard, mouse and normal/other devices? I have a racing chair with the G27 wheel from Logitech and that's 1 USB, so... Yeah, plenty stuff.
I have a B550 and I have... 3 free USBs on the back out of 10, I think? And I want to get more body tracking points shortly
