Crush your enemies, climb the tower of paperwork, or do both at the same time. Intel's Core 2 Quad Q9550 not only makes it possible, it makes it easy. The Core 2 Quad Q9550 has quad cores that run at 2.83GHz and shares 12MB of L2 cache.

Quad cores means true multi-tasking and multi-threading. Tasks or threads get their 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 handles the usual action on your operating system, while the second can play a DVD on the TV, the third download a file from internet, and the fourth one sends audio to the kids in another room with no lags or stutters. All this is made easier with Intel’s advanced Digital Media Boost.

The 45nm Intel Core 2 Quad processor is armed with Intel HD Boost, which implements new Intel Streaming SIMD Extension 4.1 (Intel SSE4.1) instructions for fast high definition video editing and encoding, enhance the multimedia performance.

  • newegg Intel Advanced Smart Cache Intel Advanced Smart Cache Technology dynamically allocates the shared L2 cache to each processor core based on workload. This efficient, multi-core-optimized implementation increases the probability that each core can access data from fast L2 cache, resulting in significantly reduced latency for frequently used data and improved performance.
  • newegg Intel Wide Dynamic Execution With Intel Wide Dynamic Execution, each of the four cores can complete up to four full instructions simultaneously, improves execution speed and efficiency, delivering more instructions per clock cycle.
  • 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 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.

Marvelous! 8/21/2018 7:06:01 PM

Pros: 11 year-old rig, and still going strong... I've built 2 others, with more "modern" components, but I kept coming back to this beast.... runs anything you can throw at her! I'll never let her go...

Cons: None.

Overall Review: If you have the $, buy it... you may not need it now, but keep it in your pocket...

WOW JUST WOW 2/24/2018 10:53:42 PM

Cons: not a Ryzen

Overall Review: a must have for the endurance

STILL ROCK IN 2017 5/22/2017 12:34:23 AM

Pros: -Perfect for a cheap build

Cons: -No RGB
-Cannot put more than 5 eggs

Overall Review: O.C to 4.1ghz on a P5Q-Premium with stock fan lol. This beast won't die and will never die. Thats why i'm on LGA775 since 10 years and probably for the next years..

SERIOUSLY, 775 is the greatest socket ever made.

Still running strong after almost 7 years @3.95ghz 11/29/2016 11:08:57 PM

Pros: -Still has great single thread performance, not on top by any means but it's more than enough for games still.
-Was a great price when i purchased it.
-Rock solid been running almost 24/7 close to 4ghz @1.3v
-Handles windows 10 easily

Cons: -No hyperthreading
-Old?

Overall Review: Board is a evga 790i sli so even tho it's on an nforce chipset it's had little to no problems with the overclock. Will run @4 but i wanted to drop core voltage. Probably not worth buying today unless you want to resurrect an old machine for some reason :) -- * Please note i'm not advocating overclocking for all as this can toast your hardware in the hands of someone who is inexperienced, just saying the chip has put up with it for a long period of time and still handles games today well at this speed :D

Great Processor still today. 8/20/2016 8:56:02 PM

Pros: Okay. I bought this processor in 2008 and I've never overclocked once. I'm currently running it on EVGA Nvidia i790 MoBo with EVGA Nvidia 730 2gb LP 5Ghz and 650w corsair pw and 4x2gb 8gb of 1333mhz ddr3 2ch and 240gb fury ssd and this old beast still running today. When ever my system dies I'm gonna upgrade. This processor is still awesome.

Cons: Cons on this processor please.. no issues yet besides it's 8 years old. Some people laughs that it's 8 years old but thing is that newer isn't always better. I've done a lot of research that today processors are more likely to last for a year to 4 years.
