Hi guys, After saving for what feels like ages, I'm finally getting an iMac However, I don't want to rush things so I make sure I'm buying the right iMac. I'm definitely getting the 5K 27-inch iMac, so that limits the choices already. I also really want a Fusion Drive. So now I need to choose a CPU. There is a price difference of 288 euros between 3,2 GHz (Turbo Boost 3,6 GHz) and 3,3 GHz (Turbo Boost 3,9 GHz). Is there really a huge performance difference between these two? Should I even think of getting a 4.0 GHz CPU? I'm a web and graphics designer and also plan to do some video editing as a hobby. I also like to play a game now and then, but I have a gaming console for graphic intense games. Games like Diablo 3 etc should be no problem I guess, as they run seamless on my MacBook (Intel Iris 1536 MB). Also, can you still upgrade the RAM by yourself on the new iMacs? I think the Apple RAM is a little overpriced, you might as well buy the RAM elsewhere and upgrade it by yourself.
