3930K in 2018: Still a monster

Pros: -fast
-fast
-did I mention fast?
-fast

Cons: -boards are expensive
-dead socket

Other Thoughts: Due to the absurd spike in DDR4 prices over the last few months, I traded down from a 7700K to the 3930K since I could get 24GB of DDR3 locally (and on the internet) drastically cheaper than 8GB DDR4. Final Fantasy XV forced my hand in my decision: I cannot say I regret my decision. Coming from the 7700K and 8GB DDR4-2133, this CPU even six years later is a forced to be reckoned with. Cooled with a Swiftech H220-X, this monster runs around 60c in gaming overclocked to 4.20GHz. I see minimal difference in this at 4.2 and the 7700K I had before it in gaming. Forza Horizon 3 at 1440p maybe 3-4 frames less, but still 57fps compared to 61fps is splitting hairs. No differences in Shadow of Mordor, NBA 2k17, Nier: Automata, or Final Fantasy XV, for that matter. While LGA2011 is a dead socket, this chip is reasonably cheap ($100 on certain websites that start with e) used and still performs with the best of them. I'll have this chip for a long time to come.

Best CPU I've ever bought, for it's age!

Pros: I bought this for my first build that I did on my own, back in 2011-2012. This CPU is still kicking everything's behind even now. I've never really overclocked, mostly cause I was scared to, and I don't see the appeal to it. This baby plays every game I have. from emulated games to GTA5 and other heavy games all maxed out and around 60fps...but the lower fps is probably due to my 1060.

Folks never really say how cool CPU run, so for me, it runs around 20c to 30c idle. When I play games, or do some editing, it goes up to maybe 50c. This is without a water cooling setup. I also, don't give to craps about some noise, and I can tell you, my heatsink fans can get load.

All and all I would buy it again, but as technology gets better each year, this CPU is just a tad to expensive for old tech, to want to invest in.

Cons: The only con I have is it seems to be running a bit weird lately, but I have my suspicions this could be due to my motherboard and RAM, and the fact I've never replaced the thermal paste. Other than that, if this baby is on sale, totally get it, other wise, why the hell would anyone spend $650 (which is more than it was 7 years ago, by the way) on this when they could get a newer gen for less.

Other Thoughts: My build:
3 TB HDD
2x 1 TB HDD (Backup drives)
250 SSD (upgraded from 2x 120 SSD)
I7-3930K 6-core
Thermaltake Frio Advanced Heatsink
ASUS Rampage Extreme IV Motherboard (Like I hinted in the Cons section, this motherboard that I have, has a few non-working RAM slots, which I think could be screwing up my computer)
RAM DDR 3 16 GB 1600 (or 1333? I'm actually not even sure anymore, in the BIOS it say 1333, but I thought I bought 1600)
EVGA GTX 1060 6gb GDDR5 (upgraded from a AMD 7970 3GB GDRR5)
EVGA Supernova G2 1000 watt PSU
Cooler Master HAF 912 Advanced Full Tower

Others:
ASUS AC3100 Router
ASUS PCE-AC68 Wifi Adapter

Lost the Silicon lottery on this one but it ran forever

Pros: This thing ran for years on an Asus Rampage IV Extreme board until I replaced it with a 4930k. I had a Watercooling setup with it. The temps at 4.6ghz were alright and they never exceeded 68c despite having to give it over 1.4v to get it to run at that speed.

The sad part is I built this system in early 2012 after the c2 stepping version came out. I didn't get around to overclocking it until 2016. It ran daily with the XMP profile enabled and all cores clocked to 3.8ghz. The main reason I built this was for streaming and benchmarking, which I didn't get to until years later because Work called.

It's great having a multicore CPU. My son used the 3930k system to do things from running virtual machines and game recording. P2P file sharing never got out of hand. Well futureproofed. The system runs games great a 4k with a GTX 1080ti. You could clock the 3930k to a safe speed like 4.2ghz to 4.3ghz and it would still do wonderful for 60fps gaming at any resolution.

Cons: I could see trouble when I overclocked it to 4.3ghz and it needed 1.25v. I was able to get it to 4.5ghz at reasonable voltages but 4.6ghz was a stretch. Last year I found a 4930k going for a great price so I jumped on it. The 4930k I got can do 4.5ghz at 1.375v, and it can do 4.6ghz at 1.41v, which is roughly the same as what my 3930k can do. The 4930k I got was an average chip. The 3930k I got, had to have been in the bottom 10% to 20%.

This was all kind of disappointing since I heard people were hitting 4.7ghz to 4.8ghz with the 3930k...... and my 2600k could hit 4.8ghz at 1.345v and 4.9ghz at 1.43v. I couldn't pay my 3930k to do 4.7ghz.

Other Thoughts: If you run a CPU at stock speeds, make sure it's not overvolting it's self, and you have a good cooler, then the CPU will last a very long time.

The 3930k is now $99 used. If you got lucky and found an x79 motherboard for cheap then you could build yourself a really good system. If you want the best of the best then look at the E5-1660 which is Sandy Bridge or the E5-1660v2 which is the Ivy Bridge variant. These are the higher binned versions of the 3970x and 4960x. If you're looking to overclock then these are the chips to get.

The best investment I have made.

Pros: This was the first CPU that I bought for my build in 2011. My system is still running strong a lot of it has to do with the stability of this CPU. One of the stock fans on my Ausu GTX 680's went out I got a cooler for it and that has been it in 6 years+. I hit the power button and it boots the same way it has for years every day. I will never buy another type of chip it is intel for me forever!

Cons: as far as I have found there has been no cons what so ever with this chip

The true best from Intel

Pros: I have been using this chip for almost 7 years ,bought in Nov. 2011 . It has never failed once . Runs everything and anything. I have overclocked it many times with good cooling and always stable. Have it pushing 2 660ti nvdia. It is a great chip. If you have had a problem with this one its all you not the chip.

Cons: It has 40 pcie data lanes but only runs at pcie 2.0 not 3.0 but I never see the difference.

Other Thoughts: Put micro code tweak or fix to run pcie 3.0 and yes I would buy another but I dont need to mine is just fine

Awesome Processor

Pros: FAST! 6 cores, very overclock-able. Stable at 4.6GHz on water. It's been overclocked since the first week I bought it. I've had this for several years (it's 2017 now) and I'm still satisfied with the performance. this processor costs more now than I originally bought it for back in 2013.

Cons: Cost...as usual but not enough to take an "egg" from the rating.

Great chip

Pros: -Long running, no issues. I still have this in my build as it STILL works great. Yes, i Cannot come close to the numbers being put out by newer hardware, but I didn't pay for that newer hardware either and I am still getting by.

-I keep track of temps and performance and the temp with the Thermaltake water 2.0 on is very low. I never see it very high t all.

Cons: none really

Other Thoughts: I still use this and will until I am forced to upgrade. I did upgrade my graphics cards to GTX1070's from MSI GTX680's in November to take the graphical load off and major difference. Processor and board when I see something that shows promise.
