Hi guys. I'd like to buy the GT 650m/Fusion Drive 21.5" iMac (27" is not an option) although I'm unsure whether or not to jump on the 16GB ram and i7 CPU options. I want something that will last me for at least 3 years with good resell value, and I'll primarily be using it for multiple-tabbed browsing (incl. YouTube), word processing, Skype-ing, iTunes, light movie editing and moderate gaming (Guild Wars 2, Diablo III, etc)--possibly all at the same time, even. When it comes to ram, I did some tests on my current computer with a bunch of applications open and found that I was generally using up around 3 or 4GB, though that would fluctuate if tabbing more/gaming. Thus, I understand it, the 8GB option would suffice here, however will I be future proof? I know the ram from Apple is expensive, but since it's not user-upgradeable on the 21.5", I don't want to be potentially bottlenecked down the line. Yay or nay? As for CPU, I've read all about how the i7 is only necessary for people who do intensive graphics-based activities and the like. That said, if we disregard that the i7's features aren't useful for everyone, the base 2.9GHz Quad-core Intel Core i5 (Turbo Boost up to 3.6GHz) is still less powerful in Ghz than the 3.1GHz Quad-core Intel Core i7 (Turbo Boost up to 3.9GHz). I guess my main question is, would there ever be a point when that extra bit of CPU grunt would come in handy for me? Or is it REALLY only for the kinds of people described above? Thanks for the help. Any further tips and info is much appreciated!
