4 out of 5 eggsNice

Pros: Phenom is a fair product at a reasonable price. I am able to transcode video using stock cooler WITHOUT reaching dangerously high temps.

For day to day use this processor is almost overkill. Capable of gaming or rendering audio/video at an entry level.

Cons: 95 watts is a lot of energy and this thing does get hot when running at 100%.

Other Thoughts: this was a quality product AMD needs to bring back the Phenom series.

5 out of 5 eggsExcellent overclocker

Pros: Runs great at stock speeds and hardly ever reaches full load unless using Prime 95. Once I put on an aftermarket cooler (Enermax E-40), I have reached 3.825ghz stable with temps 33c idle and around 54c using Prime95. I am just now overclocking after a year of ownership to squeeze more life out of it.

Cons: The cooler sucks, idle temps were 45c and up to 63c gaming and 80+ during Prime95 with stock clock...

Other Thoughts: Better and unlocked cpu's at same price range now.

5 out of 5 eggsGreat CPU

Pros: quad core. still runs every game you throw at it today. Fast for every day use.
Mine's overclocked at 3.9 GHz in an MSI 970 board(will be upgrading to an FX cpu soon) and with a good heat sink it stays below 50C under 100% load(Prime95).
with it overclocked to 3.9 GHz my benchmark scores are as good as the X6 1055T's
95 watt TDP means every motherboard supports it

No overclock with a Rocketfish heatsink(identical to the 212+) keeps it at almost ambient temp at idle and 16C over ambient at 100% load

Cons: HEAT... this thing in a case with no fans with the stock cooler hit 70C under full load with stock settings... I wasn't even able to think about overclocking it until I bought an aftermarket heat sink, case, and some case fans

Other Thoughts: Haven't found a reason to upgrade yet since I can still play games like BF3 on ultra and get 35-45 FPS so my current setup is
PH II X4 945 @ 3.9 GHz
Radeon HD 6770 overclocked(MSI)
2x4GB 1600 RAM(1450ish because of the FSB overclock)
hitachi 500GB Sata II 7200 RPM HDD
MSI 970A-G46 Motherboard
XClio 320 Case with 2 Rocketfish 120mm fans

5 out of 5 eggsQuite possibly the best series of AMD processors of all time besides Thuban.

Pros: Where to begin, power, speed, stability I mean this thing rocked my PC to life for almost 2 years after my 6000+ wasn't cutting it back in 2010. One of AMD's greatest benefits have always been socket support, My old asus am2 m2n-sli deluxe board ran this AM3 processor just fine after a simple bios update. The only I had with that whole thing was I originally bought a 940 which is essentially the same thing unlocked but AM2+ socket no DDR3 support only DDR2. Well that's great same processor, only my m2n-sli didn't support the 940 AM2+ but it supported the AM3, strange right? Way to keep it confusing Asus, although I didnt mind because I learned later how much better the 945 purple box was anyway. The 945 being 95w was a lower power consumer than the 940 being 125w, so that was a plus, another plus was the fact that it had a DDR2 and DDR3 memory controller, so I could upgrade to a newer board and newer memory if I wanted to. Which I did eventually, only not to the this lovely Phenom II but to an Intel i7. Now I know what your thinking why the hell am I giving this thing such a high review, because honestly at the time this was performing closest to an i7 900 series for only 1/3 of the price. And like I said it was still a great processor the Phenom II was one of the best processors. The Phenom II X4 900 Quadcore processors benchmark than newer 4100-4300 series even though it's clocked a good 500-700mhz faster. PII X6 benchmark better than the newer 6100 series six cores which mind you are clocked a good amount faster too, and arguably still better than the newer 6300 Vishara series, so lets not count these guys out yet amd should bring back Phenom III Logo with new architecture and return to the roots and strike back at Ivy bridge with performance instead of just clock speeds.

Cons: None at all.

Other Thoughts: My rig now is a lot different than it was back then but this processor is still a great deal to a budget gamer or entertainment/work PC enthusiast.

5 out of 5 eggsReally like

Pros: 2 more core than previous cpu, had athalon II 250, same speed. Bought 2 to make computers for my kids to play games against each other on home net work.

Cons: Not a 6 core :(

Other Thoughts: Currently only running 1, building new comp for myself so can give both to my kids. Currently running Msi870-g45, 8 gb PNY DDR3 1333, Evga gtx 460

5 out of 5 eggsHighly recomend

Pros: wow where to start first runs cool and steady all the time
when overclocking i put it to 3.4 ghz and my motherboard didnt have enough power to support the speed.
i clocked it back down and it works fine at 3.1 ghz.
being a 95W processor it draws low power and this creates low heat and allows it to run on old AM2 mobos like mine.

Cons: stock fan is ok but i would recomend an upgrade if you want to overclock

Other Thoughts: i am using a zalman cooler
intel will always have faster cpu's you get what you pay for a $1000 processor from intel will run like a $1000 processor. amd gives us close to performance for a fraction of the cost. therefore amd gets my dollar.
this is about like the speed of an i5
WEI of 7.3
my brothers i7 2ghz gets a WEI of 7.4 for $100 more than this your decision do you have that much money?

5 out of 5 eggsbest processor i have ever used

Pros: fast, reliable, and inexpensive
an epic win for amd

Cons: not a eight core

1 out of 5 eggsUsed CPU in retail box

Pros: This is a fine CPU. My son has one in his computer. It handles the games he plays and runs cool.

Cons: I have purchased two of these from newegg in the retail boxes and found bent pins on one, and stains and crud on top of both of them. This CPU has been around for more than a year. I suspect that some people have upgraded their computers, reboxed their old CPUs, and resold them.
