I currently have 4GB of RAM (DDR3) I believe.....installed on my brand NEW Unibody macbook Pro. I will need to run Windows with Fussion on it. I've seen my co-workers and it runs super slow since you have to dedicate your memory to the windows side as well. What is the cheapest/ Best way to upgrade to 8GB ?? or maybe even 6GB? I saw Apples site and they want $1,200 for 8GB which is just freaken INSANE when memory these days is so cheap. Any ideas?
