5 out of 5 eggsAwesome CPU

Pros: Very overclockable (got mine to 4.4ghz on 1.27v on the vcore)
Stays nice and cool when using proper aftermarket coolers
Future proof for years to come

Cons: Expensive

Other Thoughts: Great CPU to buy, although it's semi-expensive it's the cheapest of the three new i7 2011-v3 CPUs you can purchase so it's the best bang for your buck in a budget system.

5 out of 5 eggsGreat Chip

Pros: Overclocking a breeze, I think i won the lottery on this chip.
4.5ghz @ 1.274 w XMP enable @ 2800

Love this new chip. This is my first Intel chip and its worth its weight in gold.
Its bigger brother has more PCIe lanes but if you only plan on using 1 or 2 graphic cards this is the way to go.

Cons: NONE, all around beast.

5 out of 5 eggsAMD no more.

Pros: Reasonably priced.
Fast.
Powerful.
Worked out of the box.

Cons: Can get hot unless you have a better than average water/fan CPU cooler. Spend the extra $ is worth it.

Other Thoughts: I used to have an AMD 8 core processor. Was I wrong the entire time. Once I installed this chip in my new rig I could tell why most people prefer Intel over AMD. Don't get me wrong though, the price is what really lured me to get it. There are some Intel processors that can be very expensive but I don't need all that power. Even with this $400 chip Battlefield 4 is running at 60 solid fps on ultra setting with 140% resolution scale on a 120hz monitor. I'm sure I could do even better, but I guess my GTX 780 can only go that far. We'll see what Nvidia has to offer in the future, which I'm sure will make my fps increase even more (I don't like the 900 series so we'll see what comes after that)

5 out of 5 eggsIntel Core i7-5820K

Pros: The pro's of the Intel Core i7-5820K are the 6 core's and hyper-threading for under $400 is a great deal to me, especially when you overclock it to 4.4 Ghz at 1.252v and only only hits 68 degrees under water.

Cons: yeah... none!

Other Thoughts: The Intel Core i7-5820K was so easy to overclock it really only took me about 20 minutes to get it dialed in, one thing is that the cpu cache ratio does not really like to be overclocked to far, for me anyway I could only get it to 3.8 Ghz, but it could just be me,

4 out of 5 eggsQA Needs work

Pros: Shipped fast
Speed of cpu, plus it has 6 cores/12 threads

Cons: I have been building my own rigs now for a longtime. I have never seen such low quality from Intel. I can only hope that they missed QA on my CPU by accident.
Issues with my CPU:
1. I literally looks like the side of the metal encasing have been ground with a dremel tool. Edges have a very rough metallic drilled appearance.
2. There are striation-like gaps in the top of the processor that look like they have used cheap metal (long deeper than normal divot like grain appearance).

I am sure that this causes higher heat due to less surface area which is why I am removing one egg (POOR QUALITY ASSURANCE!!!!). Come on Intel, I have always paid top dollar for your products because of quality.

Other Thoughts: If this cpu fails me due to poor quality I will probably seriously take another look at AMD. Even though AMD is not on-par with Intel yet.

5 out of 5 eggsAmazing Chip

Pros: Super easy install.
Runs fast as lightning with DDR4 Ram
high quality construction
6 cores
Its a K Chip so it overclocks good.

Cons: Still a new chip

doesn't come with a factory heat sink

Still some glitches with the bios but that is par for the course for new Technology but its great.

Other Thoughts: The next Generation of DDR4 and amazing speed is here. The only difference between this and the 5930 is the PCI lanes. But unless you are a super power user you will not notice much difference. The price is great considering the power that you are getting. Which is AMAZING.

5 out of 5 eggsGreat For The Money

Pros: I bought this CPU as an upgrade from a core i7-975 X58 1366 socket CPU. That one ran well but was a difficult overclock. Windows 7 showed a windows experience score of 7.6 and with a 20% overclock it went up to 7.7. The 5820 shows a score of 7.8 without any overclocking. I read the initial reviews when this came out and it was clear that the Haswell-3 would not be a good overclocking CPU. I have slowly been working on the overclock and so far have only achieved about a 15% speed bump.

Cons: Poor overclocking but I knew this was likely when I bought it.

5 out of 5 eggsThe Sweet Spot for Haswell E

Pros: Handles multitasking very well and even while programs in the back ground are pulling power running cpu heavy games like Dayz is a breeze.

Cheaper than a 5830k , for the extra price you can't justify some extra pci lanes which will only even matter if you are running a 3 way sli/crossfire. (For gamers the most stable sli-crossfire config is 2 cards)
Cheaper than the 5960x, for gamers such as myself 8 cores is entirely overkill, this cpu is overkill for gaming and multi-tasking.
Much better proformance than the regular haswell cpus (including the devil's canyon editions)

Overall this chip is price to performance king for this catagory but just because it is the performance chip of the haswell-E series, don't think it isn't a seriously powerful processor.

I can reccommend this chip as it is a nice overclocker got it to 4.4GHZ stable, as more games use hyper-threading it will become evem more of an overkill for gamers like myself.

5820k oc 4.4GHZ -cooler corsair h100i

16 GB corsair Vengence 2400mhz

2.5TB Seagate SSHD hybrid drive
1TB Seagate 7200RPM HDD
Corsair HX850 gold+
Thermaltake A-71 Chaser case

Cons: As it is a 2011 chipset it does limit your upgrade options in the future but if you are a gamer, it will be a VERY long time before there is a game which can challenge half of this chips power.

Honestly if you really are worried about future upgrades just save up your pennies and dimes till the 5960x becomes more affordable.

Other Thoughts: In the end I can full heartedly reccommend this chip to gamers, video editors, enthusiasts, and other pc users who require an enormous amount of cpu power.

NOTE: for gaming this is a complete overkill but I use it so I can run as many programs as I want on separate screens as well as not sacrificing any proformance

5 out of 5 eggsHTPC Monster

Pros: This thing is amazing. Bought it to finally replace my P4 3.4ghz EE 478, and I hope it lasts just as long. Because it's a low profile HTPC I'm relying on air cooling, but it seems to do just fine on that. ~37 idle and 55 under moderate load.

Cons: none
