Stock speed is 3.2Ghz which is pretty decent for 45nm Propus core. Has a TDP of 95 Watts and runs really cool, no suprise. I had my doubts and took a gamble (not much at $90 Bucks). I installed the chip in my ASRock 990fx Am3+ board with a H100 cpu water cooler and it ran like a charm. I wanted to get the most for my money so I researched ALOT on OCN and other sites about how to overclock. I ran into minor problems but managed to get to higher and higher frequencies. When I got to 4 Ghz at 1.3875 Vcore I was pretty satisfied. Temps were only 50c 3 hours of blend testing in Prime95. After more reading I discovered I had roughly 18c more I could go before I needed to start worrying I was gonna fry the chip. I tried to go to 4.1 Ghz and hit a wall in the voltages. I needed 1.45 volts to get to 4.1 than 1.46 for 4.2 and than another big jump to 1.5 for 4.3ghz where I stopped at for my 24/7. I just couldnt imagine it could take anymore than this. I am VERY satisfied with this little budget quadcore and By overclocking it 1.1ghz over stock frequencies I think I got my money's worth. Cpu nb is at 1.35V (2710Mhz) and HT is at 1.2v (2180mhz)
I would highly recommend this processor to anyone as it does everything I ask it do to and extremely quickly and efficiently. Can it keep up with a 980? Heck no but its also 2/3 cheaper for maybe 20% less performance. I like that ratio. If you have any questions about the 840 just PM me and I will reply asap. I have had 2 of these chips now (sold one) and have yet to see a 24/7 overclock of this cpu higher than mine. Thanks for reading hope that it helped your decision!

runs very cool and has decent stock clock. With proper Board and cooling it overclocks awesome! (got mine to 4.3G's)
I think this is a great little processor from AMD. Being a quad core for such a low price is very cool, It's also very cool running and has a decent amount of OC potential, giving you have a good enough cooler and motherboard.
The processor ships in a small box with very small cooler with thermal paste preapplied, very basic manual and warranty information, and a case badge.
I have this processor installed in a system with 6gb of DDR3 memory and a AMD hd 6950. Running the processor on stock clocks I did see a 10-15% bottleneck in gpu performance in games. Once overclocked to 3.6ghz the bottleneck was remedied however. I feel running this tier processor with even higher end graphics cards would see a much larger bottleneck that even heavy overclocking wont be able to overcome.
Achieving said 3.6ghz on the core was quite simple. This processor is multiplier locked so we have to rely on blck speed and vcore. I acheived these speed once increasing my vcore to 1.35v, well within the save limits of this processor. I imagine increasing the vcore even further would allow this processor to clock even higher, perhaps into the 4ghz + domain.
Once overclocked I was able to play games like metro, battlefield an call of duty in high settings while achieving 60 frames per second. Quite a good performer for such a low price.
Cinebench scores were low compared to it's higher end amd and intel counterparts of course.
If you're in the market for a decent processor to power your low to mid range computer and an AMD apu is not an option, this could be a good processor to consider.

Cheap, Runs cool, Decent OC potential.
