Hi, I own the 2.4 GHz, 2GB RAM, 9600M-GT MBP. I'm looking to upgrade this machine. I was looking at either a 4GB (or 6 or 8? idk) RAM upgrade, or going with a SSD. Can you guys please tell me which one (or both) I should look into? Also if you could link me to some potential products (like from newegg or where ever) that I should buy, I would really appreciate it! Thanks!!
