Opinions on 6700k vs 5820k

Yes, another of these. It's tax time, and I'm planning to upgrade my 2500k system to something a bit more recent. My system is currently at 4.5GHz and has been running for over 5 years now.

So, with that said, I know this comes down to how the system is used. I primarily game with it. No 1 specific genre, a bit of everything. Recently played through things like Rise of the Tomb Raider, Assassin's Creed, Metal Gear V, etc. Running a single 980ti, which will move to the new system.

My system is also the Plex server for the house, which streams 1080P movies to multiple devices. Some need to be transcoded on the fly, but most don't. So, there is some video work here when I rip my BD movies to disk.

I also do some photography for fun, so photo editing in Lightroom is done fairly often as well.

I've read plenty about both CPUs, but just can't make a decision. I will be getting the CPU and MB from a local Microcenter. The cost will be very similar. Planning on going with the appropriate Asus Rampage MB for whichever CPU I go with.

I'm a bit concerned about some of the stability issues with X99 that I read about, specifically with memory and XMP. Planning on getting some DDR4 memory rated up to 3200. Whether or not it will run at that speed remains to be seen.

Also going to go with a M.2 SSD drive at the same time. Again, heard there have been some issues with those with X99 boards.

Planning to OC as well. I'd hope to be able to get either up to about 4.5. Sounds like the 6700k would be more likely to hit that. I will be watercooling, probably Corsair H100i V2.

I know there is no right or wrong answer here, just looking for opinions on what to go with. Fire away!
 
6700k would make a nice upgrade to your 2500k imo.
If you get a quality motherboard you'll be unlikely to have any issues.
Then you'll have all the latest features/platform and be set for another few years.
There is nothing wrong with 2011-v3 but in most things you do, I don't think you'll notice any difference. Some might even be faster on the 6700k.
 
Wait for Broadwell-E. Its just around the corner, server versions already selling 🙂

Then you may have it easier to decide.
 
you kept the 2500K for 5 years,
in 5 years I think I would rather have the 2 extra cores, with the IPC penalty which is not huge.

but for now the 6700K seems like a nicer CPU for gaming and most stuff, cheaper platform, lower power draw, better stock clocks....
 
This is using my Asus motherboard's built in automatic o/c on an Enermax ETS-T40fit:

This thread made me price a 6700K system ...
waiting for zen is hard.

Why do you want to wait for Zen? Is it to save 50-100$ if it comes in at a competitive range?
Unless you envision Zen to eclipse skylake with 10%+ performance then you're giving up 6 months * diff(skylake from what you have now +/-10%) for.. 50 bucks. Cost/benefit man, always. Pull that trigger.
 
Agreed. The next big thing is always just around the corner. If you're always waiting for that new whatever, you'll never get anything.
 
6700K. Better IPC, higher stock speeds, better OC potential, newer architecture, lower power use, cheaper, and better gaming performance today. Unless you have some extremely specific usage pattern where > 4c/8t is noticably better today, you are better off with 6700K.

The 5820K will have to catch up for general use and then some to be a better deal. There's no guarantee that its more future proof. It could catch up in 1 year, or in 5 years, or after both are outdated anyway. Unless your case is extremely specific and the benchmarks prove it, go with what is best today.
