Newegg has shipped a bunch out nothing from Amazon so far

Lets not forget you pay for fast 1 day shipping with newegg but most people like me got Amazon 1 day shipping for free if they ever get them in stock

That entirely depends on the game. I would say the two biggest genres for PC gaming are battle royale shooters and mmo's, these both can see gains from CPU upgrades at 1440p or higher resolutions.

As an aside, with 1.38v and after 30 min of aida 64 my 1700 hottest recorded temp was 68c.....on an air cooler. Come on intel lol.

On the CPU topic they didn't talk about how the i7 8th gen really make use of fast DDR 4 ram that gives extra fps even with lower end cards like the gtx 1060 and above

As has been well documented by pretty much all reviews is that Ryzen is not thermally bound on it's OC headspace thus far, and so it seems much more likely that there is some kind of instability in the chipset or the architecture itself when trying to operate at higher speeds. Most chips struggle to hit 3.9 - 4.0 GHz on high end air, and those that can still do so with temps no higher than the lower 70s on CPU heavy benches. All the reviews I've watched where they try to hit 4.1 or higher the system can't post. Could be issues with memory control, maybe power delivery issues, maybe issues with the NB frequency at high clock speeds, who outside of AMD's CPU team knows for certain, but it certainly seems that something within the architecture or the chipset is the limiting factor... Once the limiting factor is removed, getting Ryzen into the 4.5- 5.0 GHz range will most certainly have high temps as well... Ryzen seems more power hungry, which makes sense with 8 cores to feed instead of 6... but don't act like Ryzen is some holy grail advancement. It has it's definite flaws with RAM controllers and OC. There is absolutely something going on with Ryzen to where AMD seems to intentionally be limiting Ryzen to a 4.1 hard cap on OC and it can't run any RAM above 3200.. and most are lucky to get RAM to 2933...

If this time next year, there is an Ice Lake launch with Z390 and an 8C/8T or 8C/16T CPU for the same prices we're seeing with Coffee Lake.
The longer you wait the better off you are. Just don't wait to long.

lower minimums and less big swings in fps

intel shills triggered

Why would you need a upgrade path for 8700K. The idea is to keep it for 4+ years. Also I do not see how Ryzen 7 has better mins than 8700K when both have more cores than games use today while 8700K has stronger cores due to IPC and clock speed.

they probably took a leaf out of intels book and deliberately capped the first iteration chips so folks will have a reason to buy the refresh, which will come out at a slightly faster clock speed (but still be clock limited)

as to the heat issue, it might make it into a volcano like the average intel unlocked cpu but I suspect you will find that a decent cooler will keep it below 70degrees just as it did with the fx chips despite being more power hungry than their intel competitors.... that's the joy of soldered IHS over toothpaste...

Because they are nubs and have no clue how to test CPUs.

Not sure why you felt the need to type all this out, we have known what ryzen is for 6 months lol. I was merely posting what temps intel could achieve had they soldered these things.
