Bf Bot Manager V3 software will work on almost all newer computers, that is computers produced since 2014. So generally you should be fine, but if you are running large number of strategies, placing many bets at same time or using some of extra features provided by third party then you should consider using VPS or dedicated server to run the bot.
If you plan on running 50 or more strategies with single bot then you should consider splitting those strategies and running another bot instance on second computer. That will make bot faster and more reliable.

Intel i3, i5 or i7 CPU
