Is this a good match for a new rig project to take off?
MSI Pro Series Intel Z270 DDR4 HDMI USB 3 SLI ATX Motherboard (Z270 SLI PLUS)
Intel CPU BX80662G3900 Celeron G3900 2.80Ghz 2M LGA1151 2C/2T Skylake
Thank you in advance.
You can use celeron or dual core or any processor you want. That won't make any issue at all. I suggest you choose perfect board for mining with having the 13 cards slot. Still there are any number of slot mining boards available in the market but this one would perfect to add the maximum number of cards on general size rig.
Choose the right cards giving hashes for the concern coin you want to mine. Coin also matters because the difficulty increase on various coins.
