Honestly, I've never had any real problems with performance so I don't have much advice. My old computer ran it very well until the monitor blew up, and it wasn't even remotely a cutting-edge system. Unless you're looking for the cheapest laptop known to humanity, you shouldn't have too much of a problem. But to be sure, I would recommend going on the forums, posting the specs of what you had in mind, and asking how well it would do and/or where it's lacking. There are plenty of people on there that know far more about computers (and MXS) than I.
