Just a quick question, guys. I was planning to get 2x4GB RAM very soon for my 2010 13" MacBook Pro, and I was wondering if there are going to be any downfalls or cons if I over to overload it with that excessive.. power. And I've read on some few sites stating that this is the best deal so far (http://www.amazon.com/gp/product/B0...=1789&creative=390957&creativeASIN=B001PS9UKW) to get those RAMs, but it's Amazon, and shipping will cost quite a bit. So, I was wondering about being aware of the following: 1) Type of manufacturer 2) Heating up issues? 3) Shortening battery lifespan without charge for short mobile usage? 4) Best place to get these RAMs in Australia? Thanks guys.
