Mentioned in the comments of this previous deal for the i9-9900K which is out of stock. Plenty of stock left for the KF.
For those who must get themselves an Intel i9 for the highest frame-rates in games this appears to be the cheapest way to get one, for everyone else there is Ryzen. Note that this KF version does not have Intel UHD 630 Integrated Graphics enabled.
I'm seriously considering this - my gf uses my PC a lot of her 3dsmax and Maya renderings or designs - so this will really help speed things up. I only wonder if I should wait for the 10th gen of cpu's as AMD is really pushing Intel, and I get the feeling they want to come up with something good.
