+very inexpensive
+can take high over clocking
This card is for some who likes to over clock since this thing is a beast, it can take it. Although the LGA775 socket CPUs are almost dead, I'd recommend getting the 1156 i3 or i5 instead of this to go with a 1156 board, since you'll get more use out of it.

Experience: 6 Months


- Great OC
- Well priced
- Very cool
- None
This chip with my GA-EP45-UD3P and my Zalman CNPS8700NT I can get it to 4.0 Ghz without pushing the vCore and going over 62 degrees Celsius on load. Use it mainly for gaming and just about anything else as well.

Experience: 1 Weeks


High enough clock speed without need to OC
None found so far
I bought this as part of an conversion of a dated P4 2.6 GHz, Socket 473 system. No complaints from me so far as the install was extremely easy.

Solid performance, stable chip, well priced.
I'm currently using this chip in an HTPC, and it just works. I have no intention of overclocking it, but I hear it is a good clocker! Would definitely buy again at sale price.

Experience: 20 Days


Easy to install
None that I can think of
Togeher with a gigabyte EP45-UD3R board, this system is lightening fast compared with my older gigabyte k8ns ultra 939/AMD 3000+ system. Well worth the upgrade!

Experience: 10 Days


Awesome speed to price ratio
Flimsy mount for stock heatsink
This is a great CPU for the price!! Bought it for my son's new comp. This has plenty of speed for a mainly gaming comp and still peppy enough for apps.
I was dissapointed with the mount for the stock heatsink. 2 os the pins didn't seem to want to stay locked onto the mobo. Didn't feel that I could trust it too stay on so I put on an aftermarket one.

Experience: 2 Years


Quick delivery, easy installation, no issues with performance
Stock cooler has those funny feet things, attaching a cooler from both sides of the mobo is much better in my opinion.

Experience: 2 Weeks


performance, price, pretty box
not an e8400? i got nothin'
Bought it, lapped it, OCed it to high heaven, sold it. What more can I say? Great value on a CPU. How mnay more words do I need to make a proper NCIX review?

Experience: 2 Months


Great CPU. Awesome upgrade from my e2160 that came stock in my compaq system that I won.
Heatsink Included
After changing my bios to allow me to overclock my processor this was a great chip to oc to 3ghz (I couldnt do much more with the mobo that came with my unit but hey I couldnt argue with a free computer) I built up the system with a few other spare parts I had from previous builds and I definitely have found that this was an awesome cpu. Runs Crysis along with my 9600gt on the highest level of graphics with no lag whatsoever.

Experience: 5 Days


- Price vs E8400 which is usualy 200$ instead of 150$.
- 10.5x Multiplier instead of 9x as E8400.
- 45nm
- Very overclocking friendly. On a cheap (Asus P5N73-AM) I've done 3.62Ghz from 2.80Ghz at 1.35v before Vdroop.
- 3MB Cache but barrely have any effect vs 6MB.
Very nice overclocking processor for those who don't want to spend an extra 50$ for the E8400 which doesn't offer that much more. So on a cheap board I gained 820Mhz, and that was with the (Arctic Cooling Pro) heatsink which isn't the biggest heatsink.

But it for sure doesn't compare to my (DFI DK P35-T2RS + Sunbeam Core Contact + E8400 "E0") that can go up to 4.32Ghz from 3.0, so a gain of 1320Mhz :D
