Get Ryzen 1700 oc'd to 3.8ghz if you plan gaming and botting at the same time things a beast, dual channel single side ram @3200 for now
If purely you need more bots to run get a dual E5 2683 v3 stepping 2 (not 1) on Asrock EP2C612 mb and turboboost all cores to 3ghz with a bios hack (need to edit bios firmware to allow OC on all cores), then get 128 ECC ram, then you can run about million bots. You'll need sufficient video ram and also very good cooling for the CPU's I'd guess Noctua NH-U14S on each plus sufficient power and probably triple 4k monitors will be good for suprivising the bots I'd recommend getting asus strix 1080ti in SLI. Seasonic prime titanium 1500W should be enough to power it all. Oh and for SSD if you don't get at least a Samsung 850 PRO 2tbs you'll regret it big time
