dragon age on PS3?

I asked a similar question about this and FPS games for the PS3, so, forgive me.

I have a friend with an awesome PC, and a copy of Dragon Age (the whole shebang). So, I bought the game for myself to play.

On my, uh, Mac.

It works surprisingly well, except in, well...some parts. Expectedly, it freezes and lags in those "some parts". I guess I was just hoping for the best (I don't really play that many games, anymore...).

I really want to play through this one, though. And I can't afford a new computer or anything - it wouldn't be worth it, anyway.

Is it possible to play the game on the PS3 with a mouse and keyboard - essentially "turning it into" a sort of PC version of the game, that way?
