Well like I said, the 'cache drive' is for the OS AND programs you use really often. That includes games. Unless you mod for a lot of games (I'm assuming only jka here, but I'm probably wrong) then I guess you could just get a 128GB SDD. And if even THAT'S not enough, then get a bigger one. But definitely keep an HDD lying around for other stuff and backups. Like I said, SSDs may or may not be unreliable. Just for the record, I have never owned an SSD. I'm talking from theory. Don't feel the need to take my word for it. Ask someone who does indeed own one. I can think of @@Caelum off the top of my head.
