one thing that is vastly under represented in the gaming community is MMO gamers. unlike FPS games, where you cant really do much outside the game, MMO gamers can play the game windowed had have browsers and other apps (such as Advanced Combat Tracker for Everquest2) open and running while they are gaming. when im raiding in everquest2, im generally using somewhere between 3.5 and 5gb total system memory in a comp that has 6GB of ram, though only 2.5GB at most is taken up by eq2. i have seen the combat tracker i run use up to a gig before, after parsing encounter data + custom triggers and graphing it all, a nights raiding can take its tole, but you want the parser open all raid to track things. then you can have your browser open, if you are off questing and want to look at guides, and then i run winamp with a 128kb/s WMA stream from ww.di.fm playing my goa/psy trance. gaming alone? 4gb will be fine. MMO gamer? i would recommend the extra memory. also, if you have multiple accounts, it helps a ton to have a quad core CPU, so you can run both accounts at once without system slowdown. eq2 just got an engine update which offloads some tasks onto a second CPU core (isnt perfect, second core doesnt go to 100% when it should be), so having a quad can be greatly beneficial, even if you play a game like WoW which is single threaded and has minimal system requirements, since running multiple clients at once can put a good bit of strain on a processor
