Intel Technology
45nm Hafnium-Based Architecture. Thanks to a naturally occurring element called Hafnium, Intel engineers were able to shrink the size of new Intel processors and pack more computing technology into less space. The result is improved performance with less energy wastage.

Intel® Wide Dynamic Execution. Enables the delivery of more instructions per clock cycle for shorter execution times and improved energy efficiency—accomplish more simultaneously and with greater efficiency.

Intel® Intelligent Power Capability. Turning off portions of the processor when they aren't being used improves overall energy efficiency and reduces heat production, resulting in a quieter, more energy efficient system.

Intel® Smart Memory Access. Increasing available data bandwidth means more multitasking with less slowdown—run more demanding applications simultaneously and accomplish more in less time.

Intel® Advanced Smart Cache. Placing data closer to the processing cores improves platform responsiveness and performance with a wide range of applications.

Intel® Advanced Digital Media Boost. Accelerates performance with a wide range of applications, including video, gaming, speech and image, photo processing, encryption, financial, engineering and scientific applications.

Intel® HD Boost. Available only on the latest 45nm Intel processors, this revolutionary technology takes Intel® Advanced Digital Media Boost and improves it even further, enabling significant gains on the latest SSE4 instruction set. SSE4-optimized applications, such as video editing and encoding in high-definition resolution will see additional performance improvements

Performance for Multitasking
With two powerful and highly efficient processing cores, the Intel Core 2 Duo processor frees you to run multiple software applications at the same time without compromising performance or responsiveness. Everything including email, downloading, online shopping, and video editing can be done simultaneously and with greater efficiency. No longer is it necessary to choose between work and play.

Energy Efficiency
When working or playing hard, you want to keep distractions to a minimum. Thanks to Intel's exclusive 45nm technology, the Intel Core 2 Duo processor runs very efficiently—consuming less energy and producing less heat then previous-generation processors. Since desktop PCs featuring the Intel Core 2 Duo processor run cooler, they require less cooling, meaning fewer fans and a quieter computing experience. And with energy-saving features that shut down portions of the processor when they are not in use, the Intel Core 2 Duo processor is easier on your energy bill and the environment.

By James Lin VINE VOICE on June 29, 2009
This is an excellent CPU for the price if you don't need a quad-core setup. My computer is mostly use for work and gaming, and E8400 has been able to handle everything that I've thrown at it.

The quick specs:
Intel Core 2 Duo E8400 @ 3.0GHz
2GB DDR2 800MHz
Western Digital WD6400AAKS 640GB HDD
Radeon 4770 512MB
24" LG monitor (1920x1200)

Work:
I'm a web developer so my more CPU intense work applications are Photoshop CS and the Flex SDK (Eclipse IDE). The E8400 is more than enough to handle these applications along with several different browsers (IE, FF, Safari, etc.) all opened at the same time.

Gaming:
I mostly play RPGs and strategy games on my computer. Lately, I've been playing Fallout 3 and Mass Effect, both of which required fairly powerful systems when they were first released for PC. My E8400, 2GB of RAM, and 4770 512MB are able to handle both of these games smooth with high quality settings at 1920x1200.

Pros:
- Fast and dual core.
- 45nm process means that it produces very little heat.
- Relatively inexpensive.
- Overclocks well.

Cons:
- No real cons for the processor itself, but some older Core 2 Duo motherboards only support the 65nm process Core 2 Duos, which are the E6xxx and E4xxx series. Before you buy an E8xxx series processor, make sure that your motherboard supports it first. You can find a chipset compatibility chart if you search the web for "List of Intel Chipsets".

I have had this processor for a month and it works well. I have not overclocked it yet. It is an excellent value for the price.

My main problem is that the heat sink/fan is *extremely* hard to install. I could only get three of the pins into the motherboard. I pressed and pressed and bent the board and I think I got the fourth pin in, but it was unsettling to push that hard. Both of my thumbs hurt afterward. I have an XFX 780i motherboard.

Normally it wouldn't matter, because you wouldn't use the stock cooling. However, this chip is popular partially because it can reach 3.6 GHz or more with the included fan.

Also, when I installed it the processor was set at a 7x multiplier. I easily increased this to 9x in BIOS to get the full 3GHz, but it was odd that it started at 7x.

I was undecided between the e8400 and the Q6600 until after doing some research, I learned that almost no programs take advantage of a quad core right now, and are unlikely to in the near future. With the rate processor technology changes these days, getting a quad core now doesn't make a lot of sense. By the time quad cores are the norm, there will be something way better than what's on the market now. Dual core is sufficient for 99.9 of all programs on the market!

I was able to overclock this processor to 3.8ghz using a Zalman CPU cooler at 48C idle and 56C under load. I have a Asus p5k-e motherboard, which overclocks really, really well.

Pros:

Tremendous speed for the price

Extreme overclocking potential

Intel reliability

Cons:

Pretty poor stock cooler. Get yourself an aftermarket cooler if you plan to do any overclocking.

This is the best sub 200 chip right now bar none. As the others have mentioned , it does 4 GHZ overclocked easy. Runs very cool . Its an excellent value !!

Wow, a huge leap forward from my Pentium 4 3.0GHz. I put it in a new Shuttle SG31G2S barebones system with 2GB of RAM. Speed demon. Highly recommended. Encodes video incredibly fast. Runs very cool.

I considered a more expensive Quad Core, but not sure I'd get any additional benefit since most applications can't really take advantage of it. I'm more than pleased with my choice.

This CPU ran well out of the box, I encountered no problems with installation of the cpu. The included fan/heat sink is difficult to install, but worth the effort - be patient. Win XP with Svc Pack 3 runs smoothly.

I installed the Core 2 Duo E8400 on an Intel DG35EC motherboard. The board supports 1333 MHz FSB. I did not use the CPU cooler supplied in the Intel box. Instead I used an Asus V72, which I think has a better mounting system than the Intel supplied heatsink. The system I built has been running for several weeks now with no issues. The Core 2 Duo E8400 seems to be an excellent balance between cost and performance for my needs.

I have been using this processor in a self constructed computer for over a year now with no problems whatsoever. In all my other computers, I have been using AMD CPUs. So, I thought I would give Intel a try. I am very satisfied and so I highly recommend this unit. I do audio and video work. I cannot comment on how it holds up in gaming as I do not play computer games.
