I started my 5 box a couplke of weeks back, got keyclone and maximizer set up and started killing boars, running 5 windows on a 24" screen (4 very small boxes and one bigger)

A few levels later as i needed to sell, train and get some professions, i logged on the accounts in windowed mode to avoid having to use the really small windows. Anyway, since then i never went back. At this point i only have the main window open and the rest hidden. This has materially reduced lag, makes the other characters easier to run around when they need to sell etc, and doesnt seem to have any adverse effects in instances so far. Basically its like im playing a paladin that can drop totems, nuke, sheep and heal, and as long as the others either follow or are positioned pre pulls, i really dont care about what they see.

However, im only level 19 and have no real wow experience so this may just be the first few levels being quite forgiving. So although this seems to work pretty well (and appears a lot easier on the machine - just 2 gb memory), id rather not develop bad habits early on that I will need to break at higher levels.

So the question is, am i missing something vital by not seeing the other screens? Should i bring my maximizer windows back?
