While not the strongest out there, with a quickly dropping price, it's becoming one of the best CPUs to have when on a budget.

9.3
In the end i have been running the Cpu at 4.4 ghz since day one and it runs Fantastic.

What People Are Saying Give it to me straight

Applications

I have always been a AMD fan but this chip was the best investment i ever made for my Computer i love the OC ability and performance for gaming it brings even at stock speeds.
by Boydwazup (Jun, 2012)
If bought used, this processor is an insane value for gaming.
by phillyd (Apr, 2012)

Socket

With a cpu limit at 61 degrees, keeping the 8120 down in temperature can require some tampering, especially if you plan to overclock.
by Xerosnake90 (Sep, 2012)

Multicore

If you are hindered by buget this is the chip for you i would recomend this to any one that loves AMD and wants to watch the buget for an 8 core cpu.
by Boydwazup (Jun, 2012)

Performance

I like this processor a lot due to the fact that it offers great performance if you take into consideration it is a brand new architecture that has never been tried before.

Intel has unresolved bugs too, currently there is a VMware bug found on Intel E5 v2 series processor, it leads to incorrect memory page translations when the EPT (Extended Page Tables) feature of the CPU is enabled and is mentioned as Erratum CA135 . Every manufacturer (of any goods) can have issues some times.
These bulldozer CPUs were complete a complete disaster. Because of problems with their microcode they do not run their multiple cores properly and will cause BDOS on multiple valve games and Shogun 2 just off the top of my head. Some motherboard manufacturers have released BIOS fixes but if yours hasn't you're shit out of luck. Also have fun reflashing your BIOS if your not computer savy. Still no fix from AMD. I am buying Intel from now on even though it is more expensive. On a side not..... IF you have this problem someone released a fix you must run every time you boot up that corrects the problem. Just google 'Orochi-CEG'
