2600k to 7700k or wait for 8700k?

p.1 #1 · p.1 #1 · 2600k to 7700k or wait for 8700k?


I've been working with a slightly overclocked 2600k at the heart of my system since about 2012, and with getting more into photography, the bottle neck is starting to obviously be the CPU. Current full setup:

i2600k @ 4.4 Ghz
16GB DDR3 RAM
Samsung 960 Pro NVME (running on a m.2 to PCIe adapter) for a data drive
Samsung 850 Pro SSD (OS drive)
Samsung 850 Evo (Lightroom cache disk)
GTX 1080
Dual 27" Dell U2713hm displays


It's a quick system normally, with booting into windows only taking about 15 seconds. But while running a performance monitor, I see all 8 threads get slammed every time I move to a different photo in Lightroom, and render times are ........lacking.

Side note - the NVME drive I'm running is only running at PCI 2.0 speeds instead of 3.0 which means I'm only getting half the throughput on it that it's capable of. This is because my 2600k is only capable of PCIe 2.0. Upgrading to pretty much anything gets me to PCIe 3.0 which would make a huge difference. Plus, I cannot boot from the NVME as I'm running a Z77 chipset motherboard.

So anyway, I was considering upgrading to the 6700k, but it looked like the 7700k edges it out just a little bit and has better internals, but now I am seeing that Intel just announced the 8700k which is going to be a pretty big leap in terms of performance and will come with 6 cores with hyperthreading which is the big news because 6 core CPUs were never in the main stream of CPU sales. The only problem is, they're going to be back ordered until well into December.

Just wondering your thoughts. Benefits of upgrading to the 7700k over the 8700k would be -

- Cheaper to buy the CPU by around $75-$100
- Cheaper to buy the Z270 motherboard by around $75 (8700k which is 8th gen CPU will not work in any previous gen boards, have to buy new Z370 board)
- Can buy everything right now


Reasons to wait -

- Clear performance advantage with the 8700k especially with multi-thread tasks
- Future-proofing myself a little bit by having the latest motherboard architecture
- 8700k supposed to be the best bang for your buck CPU that has come out of Intel since possibly the 2600k


I know it's a lot of info, but I just thought I'd throw it out there. Having a hard time making a decision, haha.

Have you checked the "Use Graphic Processor" in the performance setting of Lightroom?

I'm upgrading a 2500K to a 6700K on a Z270 mATX this weekend.

8700K should be a good CPU, but I'd make sure the particular Z370 board had been available for a couple of months before buying. I've been burned several times with bleeding edge, buggy motherboards that took a while to be fixed with firmware updates. Sometimes one must wait for a v.2 of the board with hardware fixes.

We have strikingly similar builds I will be waiting for the 8700k. I had high hopes for ryzen but their single thread performance is lacking. You have been on 2600k for 5 years, imo waiting another two months or so isn't a big deal. If we are lucky, ram prices will come back down and you can recoup some money vs buying now.

Sigh...you aren't playing games with your rig. You are editing photos. Stop looking at your performance monitor....hehehehe....how fast Photoshop can load? How fast it can open files and to save them? Do you batch process PSD files? If so, how fast your rig can batch process 50 files with each file over 200mb in size?

FYI, you are still using DDR3 memory!!!! Is time to switch to DDR4 and using LGA 1151 CPUs instead.

Oh yeah..don't forget to factor in a new version of Windows 10 unless you are running a retail version, not OEM. When you change your motherboard, you will have to register a new copy of Windows 10 OEM version.

Actually, since I used to own a copy of 8.1 Pro and opted for the free upgrade to Windows 10 Pro and registered it with my hotmail account, I can just keep re-installing windows without issue and it self activates Kinda nice.

I ended up going with a 7700k and a MSI Z270 Gamer M5 motherboard with 16GB of Corsair LPX RAM. I was reading more reviews about how the 8700 might be nice, but not hugely different from the 7700k.

With the OS booting on the NVME drive, photos on my 850 Evo, and the 850 Pro SSD acting as a repository for the Lightroom catolog and cache disk, converting 100 RAW files to full size JPGs has gone from taking 8:45 down to a very satisfying 3:30. Huuuuge difference. Photos are now loading almost instantly in Lightroom, too, as I scroll through the film strip. And this is before any overclocking. Very happy!

don't count on that working. i just had an issue with an intel NUC that they replaced. identical product one for one. failed to allow registration with my W10 when swapping the HD. and that was considered a legal swap. took a phone call to MS and approx. a half hour to resolve it. it is tied to you BIOS and config.

After moving to this completely new set of hardware (basically a new computer) it did say there was a problem with activation, but there was a link on the window saying "I recently changed computer hardware" or something along those lines and it brought up a window asking if "Will-PC" was the computer I rebuilt with new parts (it was), I clicked yes, and Windows was then activated. Took 10 seconds.

It's too bad that the 8700K is rather crippled like the cheaper CPUs by supporting only 16 PCIe lanes. Once a graphics card and couple of M.2 SSDs are used everything is downhill from there.

Only really a problem for people wanting multiple GPU's (or tesla cards) or a pair of M.2's and some SSD's that they hit hard. For the rest of us it's a non-issue. I agree it would be nice to be able to base a proper cheap workstation on the 8700K, but i guess this is why they have the "premium" 7800K and family.
