You should be fine. But as Mauzen said before; it can be a though one when you look at the specs. A quad-core would be best, but a duo-core should be fine. 1GB can run an easy 50-100PB. With 2GB, it's way, way more.

Edit:

Ubuntu is a good choice. It'll work out, as it isn't chewing away as much RAM as Windows is.
