I was able to get an old computer for free from work and set up a server on it. It has a I7-2600 in it(which I can put a I7-2600K with an overclock in) and 4gb of ram along with a 250gb hdd. If I wanted the best bang for buck upgrade, for better sim speed, should I get more ram or would a better CPU be better? AFAIK the server only uses 2 cores so a quad core or high isnt really needed. So would a RAM upgrade be better?
