the main thing is to have a powerful enough CPU. as long as your system specs allow for the game to run, you just need to make sure your CPU is at the high end of the system specs recommended for the game.
whats systems do you have available? the first bunch of games should easily host a mass of players on a P4, but the last two would likely need a good quad core.
Thank you for your reply.
I have a Core 2 Quad 8400.. same as my current Desktop. , and a Core 2 Duo
Would that be enough,, I just wanted to know if I really really need to get like a Xeon or Opteron or a Core 2 Duo or Quad will do.
