The 6700k smokes the 2600k in gaming. I consider $275 for the 6700k an insane deal and very clearly the processor to buy right now.

Ah, I see what you mean.
I saw GOAT status mentioned and was like "the 2600k lasted way longer than the 6700k has been out".

uhh 1.47 is pretty high no wonder your cpu is getting worse.

Yeah. But I never ran it at that(thats the highest freq I could get with the lowest voltage it was stable at stressed). Was always 4.8 at around 1.4. Even then, it should take way more than that to cause it to degrade that much within the time I've had it(friend still has a 1.5v 3930k still going strong at 5ghz and we got them at the same time roughly).

Just went back to the pc after a few months of not using it, and this was the case.

depends on the temps. some would say not go above 1.4 but idk your setup.

me myself i would never push a chip to 1.4 or higher.

How many active sockets do intel have now? It is getting ridiculous.

Like two? 2066 and 1151?

Anyway, with the BIOS problems I aren't messing around with this platform. Power consumption is through the roof but that's sort of expected with the frequencies and cores this thing is packing. Ryzen doesn't really sip power either when overclocked either, its just the nature of CPUs. But, unlike AMD, Intel's TIM + gap between IHS and CPU die just makes it impossible to keep this thing cool without lopping off the lid.

550W seems like a pretty small PSU for any fire-breathing gaming PC like what Gaffer would own

A good 550w PSU is perfect for nearly any single GPU setup, really. Even something like a GTX 1080 should be fine with it.

People putting 1000w PSU's in their budget PC builds has always been kind of wasteful.
 
Is it just me or is it a *really* bad time to buy a CPU right now? I feel like Threadripper might bring on some price wars that is going to squeeze the market down into new pricing segments but then again Intel just might not care.

The 7700K has been discounted pretty frequently these past few months, the Ryzen's as well

Bad joke based on how people always overestimate the PSU they need.

Intel might be trying to make the farce the reality

Buying a CPU is kind of a lottery. Some will suck and barely be able to overclock and some will overclock like mad and last forever. You can't say that it's supposed to be like this or that.

It is a scary time.

- Ryzen might not be the best for unoptimized games, also memory compatibility fix is ongoing

- Skylake-X is a rushed product with cheap TIM and mesh, plus usual x299 early adopter bugs

- 7700K might be replaced by 6-core coffee lake soon

This is pretty much my entire concern. It wouldn't be so difficult if Ryzen 7 wasn't such a god damn disappointment on the clock speeds.

True. But with possible 6/12 coffee lake just on the horizon buying a 7700K seems to be less than desirable right now.

It's sort of always been the case. Pick up an outgoing model for relatively cheap or wait for the newer one at retail price (if there aren't shortages alongside high demand). I plan on holding out on a near-full system update for as long as possible (3570K here), so it would be interesting see what Coffee Lake and later bring.

For strictly gaming, 7700K is fine barring the uh... heat issues. Overclocking isn't even necessary. Although Intel doesn't exactly seem keen on doing anything about that, it seems...

There certainly is a lot of movement atm and after Ryzen was rushed Intel didn't want to be left behind and also rushed i9 Core X. This is the first gen of a revived competition. If one needn't update right away and has 2 years to spare I'd say just wait for 10nm (Intel) respectively 7LP (AMD).
 
I would really love to see the 7800X overclocking asap. I could probably swallow missing out on a 6/12 8700K if I still had 28 PCI-E lanes for that sweet sweet NVMe RAID.

My 3930k gets worse by the week. Back in 2012 it did 4.9g at 1.47. Now its 4.4g at 1.47 :(
I've abused the cpu for years
Dont know how much longer she can hold on, and I really would just rather upgrade to a new rig than stay with this aging platform for another ~2 years.

Intel's mainstream is out of the question since I need the 40+ pci lanes, and Ryzen(and TR I will assume) hits a freq oc wall around 4Ghz (probably due to its LPP) making it a bite the bullet situation for badly optimized/threaded games till the next gen chips come. And i9, I'd have to get a min of 7900x for the pci lanes, which, performance problems aside, looks like it will be a furnace, and suck power if it's clocked high.

Fun.

Same boat as you though my 3930k died last January. I clocked 4.8ghz that went to 4.7, 4.6, 4.4ghz then died when i returned from work after leaving my pc on durng the day just to test it. My motherboard lights up but my cpu is completely dead. Now using my backup i7 920 3.2ghz machine. Rather than getting another i7 3930k \(they are still shockingly expensive so i see no point), i think it is best for me to make a new beast (or god), but the market is a mess right now. Probably like you, my pc is used for 3d rendering and video work primary and hard gaming secondary (project cars, etc) which was why i went for the 3930k back in 2012.

Im thinking of waiting for threadripper then get the best bank for buck cpu along with the 1080ti gaming x gpu, and 64gb 3000mhz memory for i want a god of a pc rather than beast now. I need my new PC, Thor, and if i replace all the drives to SSD NVm 920 then my Thor will become Zeus. Pushing hard but nailing down that new mobo and cpu is paramount for godhood.

I welcome any new info and guidance you can give me.

Still on a 2500k currently, I feel its really holding my 1070 back as have a 144hz monitor. Itching to upgrade but might wait for Coffee Lake
 
This feels like an awful time to be looking at building a gaming PC if you've not been following the tech for a few years, between all the current Intel stuff, Ryzen, Threadripper and X299 plus all their quirks I'm absolutely lost.

I felt kinda the same way last year, everyone was saying wait for Zen, Kabylake etc... blah blah blah. But almost a year later I have zero regrets building my PC with a water cooled 5820k. It multi-tasks and games like a boss. 6 cores 12 threads ftw. The PC has also had rock solid reliability since the day I turned it on, not a single problem.

Gotcha, lol.

I was like daaaamn, I have a 750W one and I used to run a 1090t and 2x 4890's. I think with Furmark the most I ever hit was around 680W or so.
PSU are most efficient, longest lasting and quietest at ~50% load. It's doesn't cost that much more to achieve it. And, 680W / 750W is at 90% load. Long term, that's risking a PSU failure that could possibly take out everything expensive components in your PC. So, NO. The joke is on people trying to go cheap on one of the most important hardware in the PC.
 
Damn it! Why you always beating me 😝.

Edit - Woof!

The 18core variant will consume like double that. Lol

I'm still using my EVGA G2 1300w from back when I had my Tri-SLI system. I'm now on a single GPU, but still rocking that PSU lol.

Yeah. Never go cheap on a PSU or motherboard, imo.

Yes, but who's going to be taxing their system at Furmark levels on a consistent basis, for long periods of time?

Can a CPU get better with age? Either I didn't know anything about OC or something was up. Running at 5ghz but with heavy load it gets no higher than 59. I feel I can go up even more. And the thing is because of the way my room is set up I can probably get it to cool even more. My PC room is like a giant ice box.

What cpu voltage are you running for 5ghz Kadey?
 
Kaby lake-x is like those weirdly-built not so successful experimental cars that you only see in Top Gear that have the gas tank inside the seats, three wheels, or some shit.

Still on a 2600k@4.4 freaking 6 years old. I haven't kept up, what is the current equivalent?

If you want to upgrade to something in a similar price bracket? Your best bet is a 1600 hands down. If you want absolute top of the line gaming? Well, there's the 7740x(Which is advisable to delid because of toothpaste) if you want to spend way more money for a slightly better 7700k for none of the X299 features. Otherwise, 7700k is the best performer at a decent value but may be replaced soon. If you're doing workstation tasks plus gaming? Both a 1600 and 1700 is better than a 7700k for that. And, performance wise, there's no reason to get a 7600k over a 1600. If price and wattage and heat are no issue the 7900x also looks to be a better performer than Ryzen for workstation tasks and better at gaming than ryzen(but worse than a 7700k). Of course, the price difference is monumental.

In either case, no matter what you upgrade to on this list you'll see a huge improvement. Keep in mind that Ryzen boards are a bit cheaper than intel boards and are much cheaper than X299 boards.
 
Welp hopefully my year old 6700k and gtx 1070 ride out this shit storm for a few years, Intel seems to be making portable heaters out of their whole chip lineup.

AMD is very viable right now which is awesome, hasn't been like this since back with the good old Phenom II Black Editions.

When I need to upgrade again threadripper 2 will hopefully be in my cart =)
 

What stability tests have you run? That's crazy low for 5.

6700k overclocked to 4.5 is the same as a 7700k. You'll be good for a good while.

Yeah looking in the same general price range as the 2600k, only for gaming, and hesitant to buy anything AMD.

Whelp. The 7600k is in the same range as the 1600 performance-wise(1600 210-230, 7600k 230-250), the boards are more expensive too, and it doesn't really consistently perform better in games and generally has worse frametimes. If you have to go intel go with the 7700k, but that's 320-350. All of the above will give you a huge bump in performance over the 2600k.
 
Anyone familiar with what TTL from Overclock3D is referring to here with Coffee Lake?
