With 6 cores and 12 computing threads, you'll have smoother, more realistic gameplay.
12 Threads for the Ultimate Gaming Weapon
The Intel Core i7 990X processor Extreme Edition packs six computing cores running at 3.46 GHz to deliver breakthrough performance in gaming and multitasking. The Core i7 990X will not only handle today's complex games, but tomorrow's as well. You'll experience smoother, more realistic gameplay as AI, physics, and rendering are distributed across the six cores and 12 threads. Your 3D gaming will be brought to life without frame-rate hiccups and slowdowns so you can dominate the competition.

Breakaway Performance for Digital Media Creation
Whether editing high-definition videos, touching up family photos, or splicing up music, the Intel Core i7 990X processor Extreme Edition provides the processing power needed. The processor's 12 threads are optimized to keep up with the most advanced digital editing software. It also accelerates DVD encoding and compression, allowing you to easily share your HD movies with everyone. Video transcoding and compression and image rendering are done faster than ever, so you'll never be left waiting for your computer to catch up to your imagination.

Powerful Microarchitecture Eliminates Slowdown
The i7 family is Intel's flagship processor, and for good reason. With the i7 family, Intel engineers invented a revolutionary new style of microarchitecture. They replaced the front side bus--a longtime staple of processor design--with a new technology called QuickPath Interconnect (QPI). Using QPI, the Intel Core i7 990X processor increases bandwidth and lowers latency, while achieving data transfer speeds as high as 25.6 GB/s.

To put it simply, users will enjoy faster and more streamlined processing than ever before. Your computer will handle multiple projects and applications without the slowdown you'd experience with a lesser processor.

New Technologies Boost Performance
The Intel Core i7 990X processor Extreme Edition also makes use of several other cutting-edge technologies:

  • Turbo Boost Technology allows the processor to automatically boost base clock speed of 3.46GHz to a maximum single-core frequency of 3.73GHz when it's operating below power/thermal limits.
  • Hyper-Threading Technology enables more efficient use of processor resources by allowing each core to work on two tasks at the same time. This 12 way multi-tasking makes the most of highly threaded software like media players and next-generation games.
  • Smart Cache Memory increases available RAM resources, leading to less lag while multi-tasking.
Overclocker Friendly1
Built to be tweaked and pushed to the limits, Intel Core i7 990X processor Extreme Edition features an unlocked core making it easier to overclock. For performance enthusiasts and gamers looking to squeeze every last ounce of performance out of their hardware, Intel DX58SO Extreme Series Desktop Boards provide a stable foundation for a benchmark-shattering system.

1 Warning: altering clock frequency and/or voltage may (i) reduce system stability and useful life of the system and processor; (ii) cause the processor and other system components to fail; (iii) cause reductions in system performance; (iv) cause additional damage; and (v) affect system data integrity. Intel has not tested, and does not warranty, the operation of the processor beyond its specifications
The Intel Core i7 990X processor Extreme Edition is backed by a three-year limited warranty.

5.0 out of 5 stars I love it March 20, 2012
Amazon Verified Purchase
I'm upgrading from an i7 920 running at stock -- and this is a massive increase in performance. I know that the 1366 architecture isn't the latest and greatest, but I wanted a hexacore processor without also having to upgrade my motherboard and ram, so I chose this chip, and for me, it's a good upgrade. I figure this chip will keep me happy for at least 2 more years, at which time I'll be going lga 2011 (or whatever is the latest and greatest at that time)

Using Daz Studio Advanced 64 bit, a test render of "Fiery Genesis", (a pre-made, ready to render 3d scene that comes with the program to showcase what the software can do)took roughly 37 minutes on my i7-920, but this beast churned through the same render in 3 minutes and 37 seconds! Wow. I was just blown away to see such a huge bump in performance, and, despite the high price tag of this processor, for me the massive increase in rendering performance was well worth the cost. I'm aware that I could've overclocked my 920 -- just as I could OC this thing, but, in a word, I'm chicken. Even if the thing ran stable, I'd be so paranoid that one day I'd go to turn my PC on, only to see thick black smoke coming out of it. So I run stock, and it gives me peace of mind.

I'm running this on a Corsair H60 sealed water cooler, and my temps match the 920s idle, and at load -- mid 30s at idle, and about 45 under sustained load -- this is with the thermal paste that came with the processor. I may go back and try again with Arctic Silver, but that's a project for another day.

All in all, if I were building from scratch, I probably wouldn't choose the 1366 architecture at this point. However, in trying to squeeze a little more time out of my existing investment, it made sense for me, and for what I use it for, the hexacore processor made sense. I'm not really a big gamer anymore, so I'm not sure this thing is the best processor for that. Most PC games are just ports of games optimized for 5 year old console hardware anyway, which even the 920 was more than capable of handling.

I know a lot of people publish their PC specs, but I'm not in front of the 990x PC right now, so if you guys really want to see my specs, I'll edit the review and post them.

5.0 out of 5 stars WOW February 13, 2012
I use this CPU primarily for gaming, (Far Cry 1 & 2, Half Life 2 & episode 2, & Crysis just to name a few), occasionally I do Photoshop CS5, and a little video editing (home/family videos). I couldn't be more pleased. I've overclocked it to 4.4 with temps around 150 - 175 deg. I've changed the multiplier back to the default, Auto, because I couldn't really tell enough of an increase to justify the temperature. I'm quite pleased at 3.47 at 70 - 86 deg. I would definitely recommend this CPU. The only con I can think of is the price, but hey, you get what you pay for, and this CPU if worth every penny.

I use the CPU for HD video editing. Very fast and could be faster, if you know how to over clock. I was able to install the CPU with out any problems. I did need to remove the MB, to mount the fan base, so the cooling fan can be installed. Works very well.
