That's a good SSD. 120GB is a very nice size, and you can definitely keep some games on there - just keep in mind you'll have to micro-manage your data sometimes. Like the other day I wanted to download a 70GB torrent, and ended up in a real poo-poo can cause I ran out of space on my drive, as I forgot to configure my downloader's temp directory.
If you have one of the Z68 motherboards, keep in mind that you can use Intel's Smart Response Technology. With that you can use a SSD (or part of it, up to 64GB) for caching purposes. This gives you SSD like speeds on commonly used applications automatically, after about one or two runs. So you split that drive in half for OS/caching. Useful if you hate micro-managing, but only applicable to applications you run regularly (at least every few weeks, depending on how much caching space you have)
