That should be plenty for what you are describing. I run one account on a Core2Duo 6600 @ 2.4GHz and four accounts on a 2.2GHz dual-core Athlon XP with 3GB memory and a GeForce 7800GTX with a 20" monitor. I have four 800 x 600 windows tiled as best as I can (very slight overlap). With all graphics settings at their lowest, they run at ~20-25 FPS with noticeable stuttering, but everything works.

I'm going to upgrade that second system with a 2.4GHz quad-core CPU now that they're relatively inexpensive. I may upgrade the video at some point but it should do just fine for now.

What do you mean by "built-in maximizer"?
