Hello, I'm been debating on the idea whether to upgrade my 2010 i7 Macbook pro from 4GB RAM to 8GB ram, which is less than £40 from crucial. Firstly, Looking at the attached, would you say that I will benefit from upgrading? I've read somewhere that is page ins are 10% more than page outs, then an upgrade is "needed". Typically my "free" ram is less than 300MB, but we know that this along doesn't realise the need for a ram upgrade. My main problems are opening and saving large illustrator pages as well as Safari always reloading, which may be du to RAM too? I typically run the following each day: ArchiCAD, iTunes, Mail, Safari, Photoshop, Illustrator. Plus with Illustrator CS6, Adobe recommend 8GB ram... Also, if an upgrade is greatly beneficial, would crucial be a good option to buy from? They are very cheap, but I don't want some cheap poor quality RAM (that's assuming RAM has some differences between suppliers?) Thanks!
