Hi everyone, I'm just about to purchase the new iMac 27', however I'm having some doubts to what components to choose for my specific needs. I will mainly be surfing the web, downloading, playing games + movies etc. I can only choose 1 of the following upgrades. Core I5 -> I7 1TB Serial ATA Drive @ 7200 rpm -> 1TB Fusion Drive NVIDIA GeForce GTX 775M 2GB GDDR5 -> NVIDIA GeForce GTX 780M 4GB GDDR5 Which of these upgrades will provide the greatest increase in speed/fps at high graphics. I will be the way be running with 32GB Ram. Any advice/suggestions to alternatives will be greately appreciated. Thanks in advance, Mike PS: It's perhaps important to mention that the games I'm primarily running is world of warcraft, league of legends, GW2 - most likely some 1st person shooting soon etc.
