Hello, I have MacBook Pro 13" mid 2010 core 2 duo 2.4 GHz - 4GB 1067 MHz DDR3. It is recommended to upgrade my RAM Chips to those chips? http://cgi.ebay.com/Corsair-8GB-DDR...ultDomain_0&hash=item1e63b3ce27#ht_1676wt_986 They are good company? There is something else that is better?! (I will be happy for some links). BTW: I will feel the change after the replacment?! Thanks !
