why you don't calculation to buy vga cards? because with btc difficulty right now, its really hard to mining and it need take more time to get ROI.

with vga cards, you have many option for mining, you can mining ethereum, ethereum classic, monero, dash, ltc, or else. and if the electricity fee is really low, then you can get profit.
