i want to build an Ethereum mining rig with 6 R9 390 graphics card to start mining coins.

i want to know the price of R9 390 in Lagos, can someone help me find out? i don't base in lagos but am thinking of coming to lagos next month. i believe it will be cheaper there but here in benin no shop has that graphic model.

i want to invest in mining as it can pay back within 6 months.

Please recommend either laptop or desktop

for you to make $1 above online, you must invest.
