I'm going to get a new system and would appreciate your input/suggestions. I'll try to make this as quick and painless as possible. I've read a lot the threads here, spent time looking at the Public Telemetry thing, etc., and I've found several systems that have the components mentioned/listed. So, my question is this: If you were going to buy an off-the-shelf system would you go with Alienware, Dell, Hewlett Packard, or (amazingly corny name) iBuyPower? Also, is it even possible to play this game effectively with just mouse and keyboard or is a joystick (or 2) pretty much required?
