Congrats with your coin investment!
For mining, which coin you would like to go? if you already had the answer, post it here most of us could give you the good suggestion.
I assume that you're going to mine big coins only. So basically, if you want to mine BTC, LTC, DASH, you have to purchase Asic miner, for ETH+XMR+ETC, just buy AMD RX series or VEGA, for ZEC/ZEN/BTG/...you should consider AMD GTX. I think at current price, most of coins could make ROI quite fast.
