Just wanted to know guys... I have just ordered a 2Gb crucial DDR3 sodimm for my base model 2009 Mac mini. Am I to expect DRASTICALLY lower performance, than if I had used two of these 2Gb sticks?. The nature of the internet beast, is that one often doesn't know which story to believe, and let's face it - people often have a propensity to exaggerate a little, when it's simply a matter of nanoseconds that causes the perfomance 'debates'. Being quite tight for cash, I am simply upgrading my Mac mini, one 2Gb stick at a time. The next stick will arrive next week, and then, once money is back to normal, I'll order myself a nice WD scorpio black edition drive . Real life experience from people who have the same configuration would be helpful. Thanks folks.
