Unless he was reusing the memory, only difference would be 50/70$ on the motherboard. Around here the 5820K is actually 10$ cheaper, that covers the diference between a 4X4GB and a 2X8GB DDR4 kit. Not much more to it really...
Unfortunately here in Aus prices are quite a bit more.
(Plus I have expensive tastes in Mobos and Ram )
I definitely decided too fast. I should have studied parts lists a bit more, as I'm somewhat uninformed these days. But I needed the system quickly, I didn't have much choice. It's also quite a drive to that computer center, I don't want to do that often.
First I aimed for a 47xx system, because I didn't think the 6700K would already be available here. But they offered me a 6700K and an H170 motherboard, which has several PCI-slots with all features, USB3.1, eSATA, M2 and plenty more. I don't want to overclock, so I took it and bought the K-CPU anyway, because it was the only Skylake they had.
Yes, I did need new DDR4 RAM with this mobo. Luckily the prices for 2133 RAM are lower than I thought, ~$115 for 16 GB (Corsair).
In the end I am not unhappy. The system is much faster than the old one, and has all the things I had planned (eSATA and USB3.1 at the front panel, for example). I run it completely based on SSDs, no rotating HD in there anymore, and a watercooler, the system is really quiet. My previous one had had several fans and a large CPU fantower. With the imaginable consequences - noise. This new one is not even barely audible, I simply don't hear it at all when it is running, that's nice.
I wonder one thing, though - there are no fans anywhere on the chipset, yet, the tool provided with the watercooler shows temperatures between 28 and 33 degrees _everywhere_(!). None of the motherboard temps exceeds 33°, and the CPU is usually at around 30°. I wonder whether that can be realistic.
I was planning to install a fan in the side of the case, blowing directly on the motherboard to coole the components around the CPU which don't have any directl airflow being directly towards them. There are two large fans of the Corsair watercooler at the top of the case, and one even larger fan behind the front panel of the case, but none blowing directly at the chipset or the voltage converters around the CPU socket (I read they're no longer inside the CPU now).
That's the one thing I'm still quibbling with (mentally) a bit - do I need a fan blowing at the mobo now, or do the temp readings mean that I'm far from needing one.
Maybe I could also ask your advice - what is it with all the RAM types PC1600, 2133, 2400, 2666, 2800, 3000, 3200 - are there really that many different RAM speeds these days, or is most of this marketing related? Thanks in advance for all advice!
I found a review saying that while the RAM speeds really differ, their comprehensive testing showed that there is no measurable effect on application speed.
Looks like the CPU cache renders a lot of RAM access unnecessary
Yep, they're realistic. That's pretty average for any system under light loads. ie Desktop, browsing etcNone of the motherboard temps exceeds 33°, and the CPU is usually at around 30°. I wonder whether that can be realistic.
You'll be fine without a fan. If you do get the overclocking urge however and plan to up voltages you could add one to ease your conscience but even then it's not imperative unless you're consistently over the 60c mark.That's the one thing I'm still quibbling with (mentally) a bit - do I need a fan blowing at the mobo now, or do the temp readings mean that I'm far from needing one.
Basically all the different speeds equate to the quality of the individual sticks during a production run.Maybe I could also ask your advice - what is it with all the RAM types PC1600, 2133, 2400, 2666, 2800, 3000, 3200 - are there really that many different RAM speeds these days, or is most of this marketing related?

In essence the higher speed sticks are "overclocked' speeds because they can handle it. ie a PC1600 can be run at 2666mhz because it can tolerate it, but if it can't - it gets sold as a lower speed kit. With RAM it's not just the overall mhz, but the "timings" they can run at to be stable. Simple rule is the tighter the timings and higher the mhz, the more "bandwidth" or data, the RAM can deal with.
There is a small element of marketing, but it's backed up by performance. Bit of an oversimplification, but hopefully it gives enough of an idea to realise it's not all smoke and mirrors
Enjoy your new setup.
Thanks for all the advice!
My knowledge of these matters is outdated by approximately 7 years - which is when I last built a system. It seems a lot has changed since then - no fans, hard to imagine for me, I am still used to cooling being the be-all end-all of computers ☺
It's easy to lose track of technology that's for sure. Especially when it comes to all the different sockets/chips from both AMD and intel. And everything else...
I'm a reformed "fan-a-aholic" myself
Don't get me wrong, stuff still gets hot; particularly when pushed to limits - but it's built to withstand it better now. As long as you aren't up near the max temp area for prolonged periods, especially with a "stock/Non_OCed" setup then it's best just to make sure it's within normal parameters and then forget about it.
