I'd love to think that the 9900K will be within reach of many people but going by the current 6 core prices this is looking like a £500 chip. That's well into HEDT territory and makes no sense on a £150 motherboard which would get you a decent mainstream board. Add in some serious cooling and a GPU to do it justice a decent PSU and this is going to be premium system for someone with a decent income. Your average Steam gamers dream set up. In 2011 high end mainstream was £230 for a 2600K, how times have changed!
Yeah I do have to agree with you, an overall system cost these days is certainly not cheap, especially when you haven't even mentioned these ridiculous ddr4 prices (I've just had to fork out £330 for a used 4x8gb bundle of ddr4 gskill tridentz rgb 3200mhz) add that to the Nvidia tax (they seem to have forgotten the mining craze has finished). Then youre talking a system that as you say many people just cant afford.
I know as an enthusiast i want the very latest and greatest and i want to be able to buy the most cutting edge, but i have to also draw the line somewhere.
I'm personally going to have to put cash aside for a gpu....I've got the new phanteks evolx x on preorder, just bought this ram, going to buy an asus z370 formula cheaply and take the risk in hoping it takes the 9900k with a bios update. This will leave me about £700 left and that will hopefully get me the 9900k with (fingers crossed) leaving me a couple of hundred or so towards a gpu. I can't justify £1100 on the 2080ti (the Asus rog tax on the strix versions make it £1500 for the 2080ti and the 2080 £900! which is ridulous)...
Ray tracing isn't ready yet (at least at any decent resolutions), and who will have a 1080p panel then buy an £1100 gpu? Even those that do have a 1440p or a 4k screen, who will want to drop to 1080p to have Ray tracing on?
I find it all a little counter productive (for now at least). It is just to me a sort of side feature gimmick that gives us just a very small taster of what the future brings. It's certainly not ready yet in my eyes and when the 1070/1070ti/1080/1080ti is dropping like it is, there are some definite justifiable bargains to be had.
A few fps and ray tracing for an extra 500-600 over a used 1080ti price seems ludicrous to me, I'd rather sli 2x used 1080tis for roughly same money. In some games you may even get close to 144hz at 4k with AA off, definitely a shout for if you have a 120hz tv/monitor.
Anyway, back to topic...
I honestly think that if the i9-9900k is £500 to £550, it isn't at all that bad for what it offers, sure It's a fair amount of cash but that's a lot of future proofing and power there for any task. It honestly sounds a brute for the price and people also need to remember that the AMD 1800x on release was around the same price.
