hey guys, my friend and i are upgrading his MBP 2009's ram. It currently has 2gb of ram, and it just isnt keeping up anymore. he does some pretty intensive tasks and programs so he is upgrading to 8gb. But what our concern is which company is the best for our situation. and we dont know which MHZ to buy and maybe upgrade his hard drive as well. If you guys could post links of what you guys recomend would be great thanks!
