Well I have multiple accounts but I only have one that I skill on which is my main. I have just started to bot so this is the only one I am botting with so I dont know how many it can support.
same cpu and same amount of ram as me. I run 3 nexus and 1 rsbuddy with no problem. granite cpu is at 100% load i can still do it and have room for another 1-2 if wanted. however I dont have that many accounts.
