Game hard. Game often. Game at the top of the heap. Intel’s Core 2 Extreme Quad core processor QX6800 brings more to the table than anyone else. Four cores, at 2.93GHz each, with a 1066MHz bus speed, let you rule the universe with ease. Intel's Advanced Smart Cache optimizes the 8MB (2x4MB) cache system for maximum performance.

Four cores means multi-tasking or multi-threading at it's finest. Each task or thread gets its own core, no more sharing one core and set of clock cycles. This lets you turn your system into the ultimate home entertainment center PC. One core can play a DVD on the TV, the second sends audio to the kids in another room, while the other two play a game and manage the system, all with no lags or stutters. All this is made easier with Intel’s Digital Media Boost.

All of that power won't do you any good if managed poorly. That's why Intel developed Wide Dynamic Execution and Smart Memory Access. WDE delivers more instructions per clock cycle while SMA optimizes memory bandwidth. Here's all the power you need to pwn the competition!

  • newegg Intel Core 2 Extreme Quad-core Processor With four processing cores, the multitasking monster Quad-Core Intel Core 2 Extreme processor delivers twice the performance on highly-threaded applications, taking your desktop PC experience into a completely new realm of mega power. The powerful processor delivers serious performance on the ultra-demanding games of today and tomorrow.
  • newegg Supports Intel Virtualization Technology (Intel VT) With Intel VT, one hardware platform functions as multiple “virtual” platforms. For business, Intel VT offers improved manageability, limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions. In the home, Intel VT allows creating unique user environments for multiple family members using the same platform simultaneously.
  • newegg Intel Extended Memory 64 Technology (Intel EM64T) Enhances next-generation IA-32 platforms with 64-bit addressability and related instructions, allowing flexibility for both 64-bit and 32-bit applications and operating systems.
  • newegg Execute Disable Bit (EDB) Intel's Execute Disable Bit function can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system. Execute Disable Bit allows the processor to classify areas in memory where application code can execute and where it cannot. When a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage or worm propagation.
  • newegg Enhanced Intel SpeedStep Technology (EIST) EIST allows the system to dynamically adjust processor voltage and core frequency to decrease average power consumption and average heat production. Combined with existing power saving features, EIST may provide an excellent balance between providing power when you need it and conserving power when you don’t.

4 out of 5 eggsHOT

Pros: Runs very well, especially with dvd to xvid encodes and other graphics rendering intensive programs.

Cons: None.
As expected...
Runs hot, make sure your cooling is up to the job.

Other Thoughts: Those prety Zalman cpu fans won't do it alone. You need to have a more comprehensive cooling solution.

4 out of 5 eggsDefies Common Sense

Pros: Let me start by saying that I bought this CPU used. The G0 stepping of this CPU is a wonderful overclocker with unlocked multipliers and the such. I have mine stable at 3.6 GHz (9 x 400 fsb), and it is running a cool 44 to 46 degrees Celsius on the cores at 1.3725 volts.

Cons: For the price of this new CPU, it defies common sense to purchase it over the Q6600. Both start to reach a wall at 3.6 ghz, with or without unlocked multipliers.

Other Thoughts: At the price I bought it, it is nearly a sensible purchase. However fast it may be, I would not recommend this to others if they plan to purchase a new one. Also, the id number is SL9uk, which points to the older, less overclocking friendly B3 stepping. If you were to pick this up for one third its current cost, it may be worth the premium price.

4 out of 5 eggsConsider the Q6600

Pros: This is an excellent candidate for overclocking. I have a G0 stepping (which I bought used) and it is overclocked to 3.6 ghz (9 x 400).

Cons: The price is simply jaw-dropping. Both the QX6800 and the Q6600 cpus max out in overclocking around 3.6 ghz for stable, long term use. Mine is an absolute champ which I was very lucky to get used. Unlocked multipliers simply aren't worth a $800.00 premium.

Other Thoughts: How a person can be convienced to purchased this cpu (although very good) at such a high premium, I have no idea. The Q6600 is a far better choice, unless you are into absolute extreme overclocking. Even then, Yorkfield cpus can be purchased for a far lower cost.

5 out of 5 eggsSAVE SOME DOUGH!!

Pros: This is the best silicon chip ever created. World class engineering for $xx a piece. I already own QX6700 but now i want to wait till AMD introduces their "TRUE QUAD CORES." I so hope that they kill the competition so people like me and you can buy Intel's awsome chips for less. I don't care what AMD comes up with, i am die-hard fan of Intel. With this chip, intel has completely changed the rules of the game. Intel is a big daddy and New Egg rules!!!!!!

Cons: Obviously, it's expensive. $xx is a lot of money for a small chip. It happens only in America. In other countries, people don't even spend $1000 for an entire computer.

Other Thoughts: AMD please come up with quad cores so we can buy these beautiful chips for less. I don't think AMD will ever come close to Intel since the intel chips are made up of 65nm technology. Lesser power consumption VS. AMD. high power = high heat.

5 out of 5 eggsGreat Googley Moogley

Pros: This is really, really, really nice I've been waiting awhile before writing my review. But I can't help asking.
Where is that Phenom? Right here and right now INTEL rules.... Hands down this is the best processor they've ever manufactured. If you don't own one. Please save your reviews because you can't even begin to imagine the power of the beast. We are talking some serious crunching, & munching It's like you can't feed it enough. It devours everything you can put in front of it without a hiccup. We are talking lightning
blazing fast smoothness. BEST EVER!

Cons: From what I've read there are only about 1200 of these in the US. As always with Intel's top of the line processors Pricing

Other Thoughts: You really can't begin to explain how you feel every time you fire up your rig. With this chip installed. I ran 3D-mark the other day nothing over clocked 2gigs of ram, GTX and Vista. I was very surprised with my results. Only 13,000 faster machines! Imagine that! add SLI and some over-clocking I'll be playing with the big boys.
Do yourselves a favor if you are fortunate enough to have the bucks, and want the best right now without upgrading your motherboard to run DDR3 1333 buy it. You won't be disappointed.

For the record Intel requires liquid cooling? Runs nice and cool with air very stable at 40C never goes over 52C

5 out of 5 eggsTrue Quad Core? No

Pros: It is one of the best quad cores out there but all it is, is 2 dual cores smashed up together.

Cons: AMD is releasing a true quad core soon. Phenom. Seeing as how they describe it, it will kill the competetion.

Other Thoughts: AMD Athlon X2 5200+ 2.6ghz 65w, 120gb Hitachi 7200rpm, 2gb DDR2 Dual channel @ 633mhz, etc etc..

4 out of 5 eggs1.2 grand for bragging rights.

Pros: Pros... wow, where to start? This thing is a beast. Seriously. It runs BEAUTIFULLY. I have had only two lockups with this chip and that was in the first two or three days of "burn in".

Otherwise, this chip is almost disgustingly stable. I wanted to push the limits of it to see if I could make it choke so I had iTunes open, FruityLoops 3.4 processing music, I was in gmail, I had flash animations open, Task Manager, and last but not least Supreme Commander at max detail and full Anti-Aliasing--this chip didn't even sneeze at it. It peaked at about 30% CPU usage and averaged around 20%.

I'm thoroughly pleased with its performance and would recommend it to anybody that has the money to pump out for a high-end desktop. (I dished out a little less that 4 grand for my box: parts below.) I went from a 3.2 Ghz Pentium 4HT to this and wow, what a difference. Though I will say this much, that processor was an amazing business class processor and called for a very stable, reliable system.

Cons: Well first off, this isn't a true quad-core. This is two dual-cores shoved together, meaning that the L2 cache is really about 2MB per core. Not bad, really.

I've also heard that there's the QX6850 coming out that has 1333Mhz FSB and clocks even at 3Ghz/core. So for you top-of-the-line junkies out there, you may want to hold off on this one.

Last con is what everyone is talking about: heat. So, before you buy this bad=donkey behemoth of a processor, you need to ask yourself three questions: 1. Will I have enough cooling capacity to support this processor?, 2. Is my case well ventilated?, 3. Will the heat from my other hardware "bleed" into the processor?

Make sure to weigh these out, especially if you plan on OC-ing this sucker. My motherboard comes with DOC onboard, but I'm not even going to dare touch it for fear of a meltdown.

Other Thoughts: Antec Nine Hundred Case,
Rosewill RX850-D-B 850W PSU,
MSI P6N Diamond Motherboard,
Rosewill RCX-Z2 Ball Bearing CPU Cooler,
Intel Core 2 Extreme QX6800 Processor,
HITACHI Deskstar T7K500 Harddrive x2,
Patriot 2GB 240-Pin DDR2 RAM x2,
Rosewill Blue L.E.D. 120mm Case Fan,
EVGA GeForce 8800GTX Graphics Card x2 (in SLI),
SONY DRU-835A CD/DVD Burner with Lightscribe,
Windows XP Professional (32-bit).

I average about 30 degrees on first bootup, 35 degrees idle, and 41-42 degrees under stress.

5 out of 5 eggsExcellent Chip, if you have money

Pros: Excellent chip, runs under Vista flawlessly. Able to run intense applications with no sweat, even running a simulation intensive game like Supreme Commander, it never reaches more then 60-80% CPU.

Cons: Insanely expensive, lots of price fluctuation. I got mine for just under $1,300. If the price is out of your range, you can get almost the same speed by overclocking a dual core chip.

Other Thoughts: Be sure you get a very good heatsink with this chip, it DOES NOT come with a standard heatsink! The chip gets really hot really fast and has a lower temp threshold then most other chips (Intel reports that it can't go over 53C). I used, works great, keeps it around 35C idle, 48C playing games. If you value your investment in this chip, DON'T EVEN THINK about overclocking it unless you have liquid cooling.

5 out of 5 eggsPrices

Pros: What everyone else has said.

Cons: Price fluctuation. Buy today it will be cheaper tomorrow.

Other Thoughts: Was looking at getting a second on of these. But afraid if I buy now it will drop back down in price to under a grand tomorrow. Your not exactly selling petrolium here newegg what is with your price fluctuations. Up down up down. Seriously!
