I just read that Intel is planning to release Coffee Lake in the second half of 2017. These i7 chips will likely have 6 cores / 12 threads & 15% gain over Kaby Lake, if speculation is to be believed. Considering these points, would it really be a smart move to invest in a 7700K now? Does Intel always stick to their claims when it comes to release dates, or should I not let this be a deciding factor?
