I am interested in hearing everyones suggestions. 2.4GHz Intel Core 2 Duo 4GB memory 1067MHz DDR3 NVIDIA GeForce 320M 250MB SATA HDD 250GB Crucial or Samsung for SSD? (still debating 500gb or 1tb) https://www.amazon.co.uk/Crucial-MX...1465928798&sr=8-1&keywords=crucial+ssd+500+gb is what I am currently looking at Crucial for RAM as well? (is the definite maximum 8gb or 16gb?) https://www.amazon.co.uk/Crucial-DD...3&sr=8-1-fkmr0&keywords=crucial+ram+drr3+1066 Any help with picking compatible products is much appreciated, first time doing any upgrades. Looking at activity monitor I am using just about all 4GB with just my day-to-day programs - multiple tabs in Safari (a lot of YouTube), iTunes, Pages, iPhoto etc. (sometimes light Photoshop Elements 14 use) What is this about my model being a SATAII? Main point being if upgrading all this won't make a major difference in speed/less sluggish then I'm happy to look into buying the 2015 rMBP. Thanks.
