It doesn't change the fact that the i9 and the 2080ti are the fastest gaming products available and nowhere near bad products.
The problem with your argument is that you could always claim the top performer is a good product regardless of price since you cannot buy anything better. Would either the 2080 Ti or the i9 be bad products at twice the price? To you they’d just have even worse price / performance. If they suddenly become bad what arbitrary point did they cross and why is that the correct line in the sand?
I think the other poster is correct. This is a really disappointing year at the very best. Intel is pretty much tapped out in terms of CPU. All they really did was pull out the final stops to crank the clocks up to make it look better than the old baseline. In reality anyone doing top end gaming was going to delid and OC to get the same performance. Now you don’t have to do that work yourself, but there’s less headroom. If you wanted an i7 or i5 you don’t get hyperthreading any more. The chips aren’t fully fixed in terms of specter and meltdown either. Even though AMD is worth considering Zen 2 wasn’t that much of a performance bump and at best keeps Intel honest on price.
GPUs are infinitely more disappointing though. AMD has had nothing this year and even if there is a new Polaris card this year, it will be even more incremental than NVidia’s 2000 series. Speaking of the 2000 series it’s a disappointment for what you get at the price you pay. The ray tracing probably won’t see widespread use for years and there isn’t enough power in these cards to make use of it beyond 1080p, and something like the 2070 won’t even do that well. It’s cool technology and very forward thinking, but you’re better off waiting for industry adoption and a 4000 series card that will actually be able to provide playable frame rates at higher resolutions.
I don’t think either the new i9 or Ti will be thought of as good products in the same vein as the 8800 or 2700K where they were top dogs that had a lot of staying power. These will not be remembered as favorable and will likely be regarded as bad buys when people look back 5 or 10 years from now.
