Steam is a bit of a memory hog. You can mitigate this somewhat by using the 'Metro for Steam' skin, which also makes it looks a bit more contemporary (ie: like Windows 8).
We have a Steam group, as well as a few extra game-specific ones for: Blood Bowl, Dog Days, and Gary's Mod.
You can see a list of SB Steam people in the Hookup section.
