I have a 2.3 GHz quad core 15in with 8GB RAM and the factory Toshiba 3.0 SSD. I've watched Crucial and OWC drop their prices on the 12 and 16 GB of RAM and the 6.0 GBPS SSDs considerably. So when is it worth it? Do you guys with 12 or 16 GB of RAM and/or the 6.0 GBPS SSDs see any real-world differences for basic tasks over 8 GB RAM/3.0 GBPS SSDs? I'm not opposed to spending the money but unless there is a real-world difference in basic computing tasks, I don't feel a need to. I see on paper the benchmark tests all the time; however, I am not interested in figures as much as your thoughts. Thanks!
