I'd mainly use my PC for content creation (Premiere Pro, Photoshop) and would like to know your opinion. Almost all of the articles are from the 3900x's launch, but I guess there have been improvements since then in drivers and bios. In my country the 3900x is 100$ cheaper than the 9900k, and seems better in my opinion, but people say the 9900k performes a bit better in live playback in Premiere. I don't know if it's even noticeable (For those who has 3900x, is there any lag in playback?)
