You completely misunderstand memory. 4GB is the bare minimum for Mavericks, any less and even on an SSD you're delving into swap hell. 8GB is really skimpy to have just as an upgrade option, I'm constantly hitting my limits on 16GB (though admittedly my workload isn't typical).

yeah with 4GB you'll swap a lot, but as an SSD is really fast (no as fast as RAM of course, but still..) you won't notice it a lot.
