Haha... IB needs less than 2% Cpu per Bot and with the right settings nearly nothing Gpu. DB needs muuuuuuuch more

So, if you can run 10x IB on nearly full load. You cant run never ever 10x DB. Fact.
And sidenote: Thats not the lowest possible settings. Lowest settings in Core needs max 300mb Ram per Bot. There are much guides out there you can follow to reduce your Load.
@Smurg: vRam will always be the same if you use 800x600 or lower. But with 16bit it will drop to ~150mb.
@and1mixtape: i5-3570k non-oc can handle with correct settings and 2gb Grafix 12x DB without problems. oc 4,2Ghz can handle 15-18x DB, but you cant use your pc for anything else. Sidenote: A i7-3930k oc to 4,2Ghz can handle easy 20x DB or 30x IB. But you also need a 3gb Grafix. Such a system cost ~2k Euros.
I have 10+ systems and every bot on market. My lovely is the i7-3930k oc. Running 40x HB on it and its on ~70% load. But, and hold that always in mind: The more bots running on one system, the more the next banwave will hurt you! If you dont have the money, just build a decent system with ~10 bots, save more money and build another system with the next 10 bots and so on... Always remember the next banwave! And no, i dont share pics or whatever. I can give hints, take it or let it
