The Biostar gets mixed reviews, has only a 4 pin power connection not 8 on the board, no onboard wifi etc but as it's the only ITX AM4 board about at the moment, I thought I'd give it a try. I watched a decent review of it on YouTube. Guy built up his system on it and had it running while reviewing and said it was decent. Apparently the bios is a bit naff, but hopefully will have some updates to combat that, too.
I just want to benchmark it against the 7700/1080 for vid processing. Will be interesting to see side by side. Running the 7700k at 4.8 nice and easy, so will see what I can do with the Ryzen.
