If you've got trackdays and LFS, nKp, or other sim, then a PS3 just for GT5 is not worth it. Unless you just must drive real road cars and don't want rFactor... still not worth it if you've got trackdays. Plus rFactor 2 just might be good whenever that comes out.
Was worth it to me cuz I regularly play other games on it.
