Hi all, Looking to buy a new iMac in the coming days to replace my existing 2010 iMac that's going to a family member. I have a few questions that I'm trying to find answers to, so would appreciate any advice. 1. Is i7 hyperthreading used in modern, popular games? 2. Is the 4GB 780m better than 775m for games, or just video editing? I'll be playing Guild Wars 2 (Mac Beta/Windows), and some Battlefield 4. It's not primarily for gaming but if I'm going to spec it out to full I want it to be for a reason. My work alone doesn't require a full-spec iMac. If the i7 and 4GB graphics is just for things like video editing/rendering, and not particularly beneficial for games, I won't bother with the upgrades. Thanks for any advice.
