Garry's Mod Hosting 2017 - Key elements you research?

Gmod servers are single core, so you have to look for i3,i5,i7 processors. Intel xeons are something middle and AMDs are the worst. Look for sigle core perfomance if you want to host server with many players and/or heavy addons. Next thing is RAM and disk space. More players/addons - more ram, i dunno how many but for 20-30 players 1GB is fine for linux servers. SSD is prefable due faster loading but HDD is fine too. Third thing is host stability, maintenance features and tech support. One time i used cheap and powerful hosting but it had some problems and sometimes i couldnt even start my server and tech support couldnt help.
