Terraria has very low system requirements and can be played online. The first Left 4 Dead shouldn't be that bad, either. If you're also looking for a non-Steam, Ace of Spades is pretty small and doesn't lag.

I'm looking for good multiplayer games on Steam with low system requirements.
What is your favourite multiplayer game that is playable on crappy old laptops or office PCs?
