Well I've decided to upgrade my mbp because when i have more than a few applications open it does feel less responsive... I have a early 2011 13" mbp with its stock 4GB ram. I'd like to upgrade my ram but I don't really know that much about computer components so please if anyone can tell me what the best ram for an mbp would be? I don't mind it being a bit more pricy than usual and if it could be an item available on amazon because im in the UK and lots of companies only ship to the US. I want two 4GB sticks. Thank you Oh and I was looking at this http://www.amazon.co.uk/Crucial-Sod...1_1?s=computers&ie=UTF8&qid=1322316577&sr=1-1, any good? Edit : Ok I just recieved this 8GB kit from amazon http://www.amazon.co.uk/gp/product/B002YUF8ZG and installed it, feels much faster and responsive now.
