[quotemsg=21720151,0,120171]I thought you were benchmarking them... :/

They did. Follow the in-article link to their 9900K review. Performance should be identical, minus the integrated graphics. I suppose it could be worth investigating whether the KF chips are as likely to overclock as well as the K ones, but that would require a number of samples from different sources to get a clear picture, and is probably best left to reports from companies like Silicon Lottery.
As for the pricing at B&H, they are primarily a camera store that has branched out into other electronics, so it wouldn't surprise me if whoever decided on the pricing for that pre-order wasn't entirely aware of how a 9900KF differs from a 9900K, just that its a newer version of the processor. So, they might simply assume that it's something people will be willing to pay extra to pre-order. And some people who are similarly unaware probably will.
Even so, Intel really should give these things a lower MSRP, even if it's just a $10 difference. Integrated graphics might not be an essential feature on a higher-end processor like this, but they can be convenient to have. With the Ryzen 3000-series processors likely coming within a matter of months, and likely offering very competitive performance to this CPU at a much lower price, you would think Intel would try to be a little more competitive with their pricing. Perhaps they just want to get as much price-gouging in while they still can. : P
