I am going with G.SKILL due to the very very positive reviews for it here and on NewEgg. This: http://www.newegg.com/Product/Produ...na&AID=10521304&PID=4169666&SID=1qgdjq6wmw8yp and this: http://www.newegg.com/Product/Produ...na&AID=10521304&PID=4169666&SID=1un836rwfxa4z are both the exact same price but seem to be different as one has 197 reviews and the other has 135. Also the model #s seem to be slightly different so please forgive me I'm no longer the technically savvy person I used to be when I built gaming computers...what is the difference between these two sticks? Also I have a MBP 2011 corei5 with 4gb RAM which I believe runs at 1333 mhz will I have any benefits from getting faster RAM (1600 Mhz)? Lastly could anyone tell me which of these tool kits has the right scewdriver bit for my MBP? http://www.newegg.com/Product/Produ...EPA=0&Order=BESTMATCH&Description=screwdriver thank you in advance!
