there is not too many stats out there, from what i have heard artemis does not allow hyper threading or what ever its called when you have a pc with multiple cores so you are better with less but bigger cores as apposed to smaller but more cores if that makes sense, ram is not a massive thing as the game is not physically that big, the biggest issue is upload speed to the server, download is important as well but if you have a tiny upload speed the server does not get all the info from players in time and you get massive lag.
