You will be fine with an SSD if you do not have files to store. I have no idea how that other guy ran out of space with 4 or 5 games. There are quite a few good guides on how to optimize Windows for an SSD including turning off Indexing and Hibernation, not having a page file if you have more than 4GB of RAM, turning off system restore ect. that will free up quite a bit of space.
I have some decent sized games too like Skyrim, Far Cry 1 and 2, Bioshock, Half Life 2 + EP 1 and EP 2, Fallout NV, Civ 5 ect. 10 or 12 total. I do uninstall when I am done with them for a while but with Steam it's as easy as just downloading a game again when I want to play it.
