I need a new PC and after a lot of research I thought I am going to chose the 9700k over the 8700k. They seem mostly equal with the 9700k edging out the 8700k a little bit. I was fine spending $30 more on the CPU and $30 more on the MB. Also, the 9700k supposedly addressed the issue of Spectre/Meltdown. But now my son put doubts into my thoughts. I won't go with an AMD processor because the video recording software I am using (BlueIris) depends heavily on Intel's QuickSync and that is a major CPU consumer. I do no gaming but I am going to use my son's old GTX970 (he got a 2070). My main tasks are really research on the internet (I often have 10+ tabs open and that seems to consume a lot of processing), do some programming (Visual Studio), etc. So a lot of multi-tasking. So maybe the 8700k is indeed a better choice despite having 2 fewer cores?
