Hi, so I've done some research and still had to ask.. I just got the 2.3 ghz Mac mini with 2gb memory, but thinking if I should pay another $ 150 to upgrade to 2.5ghz with double ram Mainly because I might get a 3d tv soon, will the AMD graphics help with 3d? I have $50 store credit, so is it worth it? Or should I just get 8gb ram in my current Mac mini? Im mainly using this as an hometheater hub, streaming Content from other computers to my tv.
