Not sure I can return it, I didn't purchase CPU with amazon and it's not really the store's fault... is there a cheap MOBO that can easily handle 2 1070, 2 1070 ti + 1 1060 and compatible with the G5420?
Also, I didn't mention, but the only RAM I have available is a 1x16bg TridentZ that I have left from other package I bought (that I keep as a backup for my office computer) so not sure it was going to be compatible with the 110 pro btc+... wasn't a problem because I would buy the slot if needed, but now that I might have to return the CPU to perhaps end up needing one more slot, maybe better to buy a newer MOBO... advice welcome!
edit: really appreciate the advice, I was getting super frustrated not knowing what the problem was!!
Could just a proc thay works with board. Chances are it never turned on so probably no damage. They pretty smart machines.
Here is cheapest ive found:
