Really hard to say since you want exceptional holiday pricing and we're well over 2 months away from Black Friday. You also have to consider the new Nvidia and Intel lines of GPUs and CPUs will be releasing soon, and as is always the case with older gen models being phased out, their price depends on availability when the manufacturers stop making them.
Example, I recently saw Newegg drop the EVGA GTX 1080 Ti FTW3 way down to $630 with mail in rebate, but only for a day or so to push out excess stock. Other GPUs in the 1000 series have had low prices as well, but now the more elite brands and models, even the EVGA 1080 SC, are rising back up in price as stock dwindles.
Another thing that makes it hard to predict is we don't know yet how the Intel 9000 series CPUs or Nvidia 2000 series GPUs will sell. There's only been brief review site claims on 9700k performance and nothing regarding 2000 series performance. Literally nothing that consumers can really trust yet.
Some have even speculated Nvidia's unwillingness to show any actual performance benches on the 2000 series, as well as hard selling preorders of top of the line aftermarket cooled units, if anything means they are hiding something. Which might be what has caused people to snatch up 1000 series GPUs IMO.
