Like the superheroes of old, the AMD Phenom II X4 955 streaks out of the night to lay waste to your enemies with four 3.2GHz cores that have dedicated L1 and L2 caches for each , and 6MB of shared L3 cache to handle really heavy loads or large data sets.

Memory transfers get faster than ever. HyperTransport Generation 3.0 mode allows up to 16.0GB/s of bandwidth. Up to 17.1GB/s memory bandwidth for DDR2 and up to 21GB/s memory bandwidth for DDR3 memory controller delivers an amazing total of 37GB/s of processor-to-system bandwidth. This unprecedented bandwidth is needed to feed the data hungry AMD64 with Direct Connect Architecture cores.

You'd think that all of this power would be too hot to handle. Think again. AMD's Cool'n'Quiet 3.0 works with CoolCore Technology to minimize heat while keeping power and efficiency up. Now the cores can shut down unused parts of the processor when not in use. This saves power and helps to reduce the amount of heat generated. This function is built in so there's no need for drivers or BIOS updates.

7 years... and still playing modern games best investment I ever made

Pros: - has been overclocked to 3.9ghz for years without issue
-I finally upgraded to an R7, and this chip will still live on in a media PC until it dies or I do

Cons: -ran a little hot so I liquid cooled it

Best processor I have ever owned

Pros: Has lasted 8 years and still runs modern games. It's stable to around 3.6 GHz overclocking. Although I stopped overclocking it a few years ago because it wasn't really necessary.

Cons: Included fan was insufficient. It was running quite hot -- not hot enough to damage the chip, but hotter than I felt comfortable with.

Other Thoughts: I paid $160.00 for this in 2010, and I've gotten more than 8 years out of it. That's $20 a year. If you, for whatever reason, need an AM3 processor, this is the one to get.

Long happy life

Pros: This chip has been a very good. For seven years it has both warmed by room and played my games. It has been through three cases two video card upgrades, and three ram upgrades. Unfortunately it is now time to put her to pasture. I am upgrading to i5 skylake and will be retiring this proc which is almost as old as my children, You will be missed Deneb, you will be missed.

Cons: - Will heat up any room

Other Thoughts: I know this is a discontinued processor but I felt I had to say something that I was now retiring this workhorse. I was going to wait for the 'zen' proc but decided against it, I've been with AMD for 11 years now and switching back to Intel, just hope I don't regret it in six months.

Still running strong

Pros: Bought this in 2009, was state-of-the-art then, still a reasonably good performer now.

Cons: none
nada
zilch
bupkess

Other Thoughts: This and the Gigabyte motherboard were retired, then re-purposed as an audio entertainment center. Old hardware need not end up in the trash when it can be recycled at home.

What a champ!

Pros: I thought it high time I write a review on this CPU. I bought it here on Newegg back in 2009 along with the MSI 790FX-GD70 AM3 mobo and I'll be darned if these jokers aren't still running like champs! I've been contemplating upgrading,but why? I don't know, I guess I just have googly eyes for new tech, but this build along with 8gb 1600 DDR3 Ram has been running solid since that time with all kinds of gaming power. I think I have gone through 4 GPUs in the time I've owned the CPU/Mobo combo. Good stuf! I now have it on Windows 10 without issues (at least hardware issues...stupid microsoft auto-updates). Thank you AMD for a cheap solid build for cost conscience gamers!

Cons: Not a one!

Other Thoughts: Probably to late recommend buying, but great CPU if you can still get new!
