My computer ROCKS now

Pros: Upgraded from athlon x2 5200. I also have a 9800 gtx video card. I use to play FS2004 with frame rate of 30-44 with half graphics, now I am full graphics and 50+. Load times on applications are fast. It feels like I got a new computer. Easy install just pop it in and it works. BIOS automatically recognized. When I brought my first chip x2 5200. This chip was well over $200, now for $89, what a bargin

Cons: NONE

Overall Review: Don't delay buy it.

works perfectly

Pros: Very low cost because you don't have to repurchase the stock cooler you aren't going to use anyway.

Cons: I think mine was mis-marked. I tried to install it in the same orientation as the CPU I took out, but it didn't fit. I checked my motherboard manual to make sure I was lining it up correctly. The manual clearly shows the arrow on the CPU should be diagonally opposite the locking lever when the lever is straight up, and that's how I had it When I looked at the bottom of the CPU and compared it to the socket, the blank spots on the CPU were parallel to the blank spots on the socket. I rotated it 90 degrees, so the arrow is now parallel at the end opposite the locking lever arm, and it fit. I've been building PC's since the early 90's and have never seen anything like this. It works perfectly, I'm not sure how this made it through QA.

Overall Review: I installed this in an Asus M3N-HT Deluxe/HDMI, after upgrading to the 2904 BIOS. Installation was a snap once I got the CPU orientation sorted out. Dropped it in, locked it down, put the cooler back on, and it was done. I'm using a Scythe Ninja Mini CPU cooler and have noticed that the CPU idles 6 - 8C hotter than my older 89W Athlon X2 5600+. Nothing major, just worth noting that you might need to consider increasing your cooling.

Almost Didn't Make It

Pros: Reasonable price.

Cons: NewEgg shipping. The CPU was placed inside a much larger box along with a MOBO and a power supply. The CPU in a flimsy clear plastic container. No additional packing material (!!) caused the plastic CPU container to pop open during transit and the CPU ended up bouncing around the inside of the box. When I opened the cardboard box I found a CPU with pins bent every which way.

Overall Review: I carefully bent the pins back into place and ran a one hour CPU Stability Test (CPU Warming). No problems at all. It"s one tough CPU, that's for sure. Generates a reasonable amount of heat. I got the higher frame rates I was looking for.

Works perfectly

Pros: Works well, easy install, I prefer it OEM, Great Price for Great speed.

Cons: none

Overall Review: I got this as an upgrade for a 1.87 dual-core and the difference is unbelievable. I can Open up Firefox in less than a second and I can run Crysis on maximum with a smooth frame rate with my GeForce 9800 GT, and only get about 75% usage while toppling a building and getting fired at by 10 guys in Red Faction: Guerilla. I love it

Great CPU!

Pros: Works wonderfully! Relatively cheap/inexpensive for great quality. I have always loved AMD and this CPU is great example of why. Computer runs great with it - no problems with running it nor with installing the CPU on the motherboard (an ASUS).

Cons: No heatsink included, which I guess isn't really a con since I didn't realize this was OEM until after I already got it. Had to run to Best Buy to buy a ridiculous heatsink though, so I paid a bit more than I wanted to but with it the CPU is cooler than my refrigerator :-) ...

Overall Review: Great processor. Definitely a great buy, especially for a first-time quad core owner. Just make sure you get a good heatsink since it doesn't come with it.

Great Processor..

Pros: -Easy install for AM2+ slots
-FAST 2.5 quad
-VERY cheap for your buy

Cons: -Doesn't come with cooling supplies, if you your a beginner and building a computer, you want to make sure to pick this up, if you try to start your computer up without a cpu cooling system, your computer will shut down almost immediately, due to your cpu overheating BY A LOT.. happened to me a few years ago. Make sure to change your thermal paste every 3 months or less, this processor gets hot

(overall only con is it gets hot)

Overall Review: This is definitely one of those items that define the word "Value" would recommend it to a lot of people, and in fact will.
