its far bigger then the extremely niche video editors/content creators
anyway, as a PC gamer theres no reason to buy a Zen for me .. its slower now in games, it will still be slower after tweaks and it will be even slower against Skylake-X & Coffee Lake, both of which will be out well before Zen+ .. hell, Zen+ is slated for 2019 IIRC, even Icelake has a chance of coming out earlier than Zen+
every single game in existence right nowI can only come up with one scenario in my mind where someone would benefit from a 7700k
only if you're on a tight budgetThe 1700 almost makes the entire X99 platform pointless.
if you can afford the best then X99 (6900K) has about parity or slight lead vs Zen in professional apps, OCs ~300+ Mhz higher and has significant leads in games
although theres no point buying X99 now anyway, might as well wait for X299
AMD remains the budget vendor, good for them .. but I dont like to compromise if I dont have to and i7 gives me that option
