So for what the $450 the board you link costs, plus $50 for CPU and another $50 for memory, $550 total (low cost miner build components) you could build 3X the typical boards.
3X Biostar TB85 ($65 ea) $195
Except you can't because the Booster TB85 is out of stock at Amazon and NewEgg. Which is not surprising since it's 2 generations old at this point.
That's the purpose of this thread-- to find Z170 or Z270 boards that can drive 6GPUs.
If you read my whole post at the bottom I did say I thought the thread was a good idea as replacements are indeed needed. Also I mentioned the drying up of the 1150 series processor which will probably be the bigger death blow to the old school builds.
I just do not think we all need to praise $450 board nominations as that replacement though, at that price it is totally nonviable for a mining rig. The comparison I made was to show what ballpark the new board should ideally be in to compared with builds we are used to.
So once some nominations start appearing that are sub $100, or at least under $150, then we can all cheer and move on. The upcoming Biostar TB250 may be a start depending upon its retail price, but from the looks of it I am sure it will be closer to the $100 range than $450.
