Help decide please: Should I pull the trigger on a 6700K used bundle?

Hello, how are you?

I am having a hard time making a decision here.
I currently have a 3700k on an old Asus P8Z68V-Gen3 board with 16gb (2x8) Gskill Ripjaws X 2400 CL11 ram.
My 3770k is not the greatest overclocker so I run it at 4.5 1.2v daily.
My gpu is a 1080 Ti clocked ad 2000 core and my display is 1080p 144hz G-Sync.

Someone I know locally is selling a bundle with:
6700k
Gigabyte Z170X Ultra Gaming Motherboard
32gb (2x16) Crucial Ballistix Sport LT 2400 CL16 RAM.

Everything is boxed and in great looked after condition.
Now, the board is not the greatest, and the VRM worries me a bit being 4+3 phases.
But then again, the Asus Hero for example uses 8 cpu phases, but they are doubled, so I don't know how much better a board like that would actually be, and if to have some proper VRM I wouldn't have to end up spending over 200 on a board alone.

Now, what is getting me thinking is the price.
He will let me have the bundle for 400 Euros.
I am in Portugal, so EU prices.
Anyway, I think it might be a sweet deal.
GIven current RAM prices, 400 for a 6700k, z170 board and 32 gigs of DDR4 seems sweet.
But is it a good deal?
Should I take it?
It also worries be the RAM, being only 2400 since I would must use it for gaming.

Sites like digital foundry already showed that RAM speeds matter.
The ram is 2400 at 1.2v.
Would I be able to clock it to 2800 or 3000 at 1.35v?

Also, how much of a bottleneck would 2400 ram on a 6700k actually be?

I am thinking about getting it, then try an sell my 3770k with board and ram.
If I could get 300 for it, the upgrade would cost me 100.
Good deal?
Should I take it?

Also, 8700k is really nice, but it's 400 the CPU alone. So currently it is not for me.

What are your thoughts?

Cheers!

probably is worth it if you dont mind not being able to upgrade/have more than 4c/8t, but for games you will need to get better ram since 2400mhz will hold back skylake(and zen) architecture

if you need to do video editing a CPU with more cores would be useful

As far as gaming goes I don't thing the gains will justify the hassle of changing out the system or the money spent or trying to sell the old system. Especially given you are already have a decent overclock. I personally would wait for 8XXXk to come down a notch because that seems to be the better upgrade. The only real gains I see are if you play lots of GTA, otherwise its only a 5-8 is fps boost on your average FPS at the very most. Even my 2600k at 4.8GHz gave my 1700x at 4.0GHz a run for its money and I built that rig in 2011 (i know its amd vs intel but still). The improvement as far as i see is not worth it.
This was the best comparison I could find comparing the CPUs in games.

I think it's worth it. That RAM will limit you in gaming somewhat, but we're talking about a handful of frames per second. This is, of course, contingent on you being able to sell your current CPU, motherboard, and RAM. Otherwise the upgrade is fairly pedestrian and a decent chunk of change for a minor upgrade.

Something else I just thought of: you could always sell that RAM kit for a decent amount of money and buy whichever 16GB kit you want to replace it.

for 100 dollars / Euros or whatever your currency id do it , its a decent deal plus you get double the memory

the RAM ''32gb (2x16) Crucial Ballistix Sport LT 2400 CL16 RAM'' is only running at 1.2v the normal voltage for good DDR4 is 1.35v - 1.45v so you have a lot of headroom to overclock the ram

Product Description Crucial Ballistix Sport LT - DDR4 - 32 GB:2 x 16 GB - DIMM 288-pin
Product Type RAM memory
Capacity 32 GB:2 x 16 GB
Memory Type DDR4 SDRAM - DIMM 288-pin
Upgrade Type Generic
Data Integrity Check Non-ECC
Speed 2400 MHz ( PC4-19200 )
Latency Timings CL16 ( 16-16-16 )
Features Dual rank, dual channel, Intel Extreme Memory Profiles (XMP 2.0), grey heat spreader , unbuffered
Voltage 1.2 V
Manufacturer Warranty Limited lifetime warranty ( Germany - 10 years )

I think I am going to do it.
What is holding me back more than the ram is the actual board.
It doesn't have a very robust VRM. And it might be an issue.
But a good z170 board is expensive.
And something like a pro carbon or gaming pro, while looking better on paper, use phase doublers and end up being about the same.
So I think it is a good deal...
If I price these parts on a cheap online store, I end up with ate least 700 euros. So it is a good deal... Or so I say to myself...

I did it.
Picked up the bundle just now.
I will set it up tomorrow and see what it can do.
If the memory can go to at least 2800 with reasonable timmings, I'll keep it.
If not, I might advertise the 32gb kit to see how much I can sell it for.

I will also list my 3770k setup tomorrow and see how that goes.

In regard to the new setup, due to the chipset, audio drivers, and such, should I do a clean install of windows 10? Or is it not necessary at all?

Cheers

I would do a clean install you jumped 3 gens

I would do a clean install, in my experience, weird things happen when doing mayor hardware upgrades on the same OS.

As for drivers, most of it should get installed by windows automatically, but I also always download all the latest drivers from your motherboard's support page.

I'm not sure how much Windows 10 is affected by large hardware changes like that. I made a similar upgrade when I had Windows 7 and got away with foregoing the clean install. I eventually had problems that forced me to wipe my primary drive and perform a clean install. I don't know if that problem stemmed from not performing the clean install when I swapped hardware, but it's better to be thorough than try to take shortcuts.

I would keep the RAM. The timings are looser than I would like, but still acceptable. Tighter timings wouldn't give much more performance.

For gaming, what performance difference would. I get if I ran a faster kit at the same 3000 but managed cl13 or even cl12?

Cheers

You won't find a DDR4 kit with timings that tight. The lowest CAS I've seen is 14 and that's on lower frequencies. A smaller kit would probably have CAS at 15 or 16. Your timings are more than acceptable.

Yes, but generally, a Samsung b-die kit rated at 3200 cl14, can easily run 3200 cl13 or even cl12.
Doenclocked to 3000, most will do cl12 from what I've seen.
I was talking about that. Getting a fast kit with good ic and tune it for faster timmings.

I looked after my post and there's several kits with tighter timings available. Still, I wouldn't bother chasing extra performance from RAM, at least not financially. It's the worst place to spend for performance. You might see a difference of 2 or 3 frames per second with tighter timings.

I hope the performance boost was worth it. I would have held onto the 32 GB kit with the overclock you were able to achieve.

This is a 32gb kit.
It is a ripjaws v 3200 cl16 kit.
Went it cheaper hynix, but got the same 32 gigs at a faster speed, lower latency and no cost.
Will see what it can do.
