I've been a Windows user all my life and now i have decided to switch to OS, i want to buy the 21.5" iMac and since i will buy it from Europe i have to pay more for each component so i have a limited amount of money. The one i want it starts at 2.186$ it's the 21.5" 2.9 Ghz with NVIDIA GT750M 1GB and for each upgrade i have to pay 277$ and i know for sure i'm going to get the 1TB FusionDrive. I need your help in choosing the second upgrade between 16GB of RAM or the i7 processor because i can't get both. I am going to use it mainly for web design and web developing and some video editing here and there. Wich one do you recomand? Thanks.
