AMD FX is the best processors you can find for so few bucks.
Edgar Hernandez
Used alienware and many other intel platforms before, i have to say i am very impressed with the AMD Fx-4100.
Big boy
I will, for as long as I and AMD exist, buy their chips for that reason.

I've just assembled a new gaming rig with this CPU and as an AMD addict for years (decades actually), it's the first time I am not blown away by one of their new processors. I do now understand the mixed reviews the FX has gotten since its release. Now don't go thinking this is a bad CPU. It's not. It's just not what I expected it to be I guess.

First of all, the FX 4100 is a really "open" CPU, it lets you toy around with a lot of its features and options thanks to the fact that it's unlocked. People who are a little more than just computer literate will love this, cause it enables you to tune your processor the way you want it and explore its limits. AMD has done a very good job on this side and provides the tools to do just about anything you want. If you own a good motherboard (and you should with such a processor) as I do (Gigabyte 970A-UD3), you can really unleash some of the hidden potential of the FX.

The other interesting thing about the FX is that it's a semi-intelligent CPU if you will. It adjusts itself to use more or less power to execute certain tasks. Or so it should. The problem is, it doesn't seem that the software really understands that. Sometimes, you will get very good results performance-wise and then another task will just behave so poorly that it'll make you regret your old Athlon or Phenom. Another issue is that certain games for example, do not want to run at all with an FX installed. Red Faction: Armageddon is one such game. This is quite sad and honestly, it feels like the FX was just released a bit too soon, with lots of promises to wipe out the bugs at a later point in time.

You can't really beat $110 (plus currently 10$ off if you pair it with a Gigabyte Am3+ motherboard). The other new AMD processors may have more cores, but the truth is, most applications currently used at home don't take advantage of the full potential of Quad core processors, let alone the 6 and 8 core processors. To me, the added cost of buying those processors (or even any of the Intel processors) just isn't worth it right now. This processor is by far the best bang for your money (for now at least) and if you are building a new computer or replacing an older one, then I would recommend this processor.

This processor doesn't really perform all that much better that any of the Phenom II processors. If you currently have one of those processors, I would not recommend upgrading to this (or any of the other new Bulldozer processors). What little difference there is, would not be worth the cost. I would wait for the next processors to come out (I think I am hearing April for those, but I'm not sure).

I am giving this one a 5 star rating because it delivers exactly what it advertises, a solid quad core processor at an exceptional price. There are better processors available, but you will also have to pay a lot more for them.

I'll try to review this for those with average technical skills (since that's what I call mine, hah!).

I bought this as well as numerous other parts during the black friday/cyber monday sales to put together a very adequate computer. Note that this is a AM3+ socket!! At its release, a lot of motherboards didn't have the socket support for AM3+ yet, but they are definitely out now. As a suggestion, check out ASRock's extreme boards, and always do research before you buy. Furthermore, try not to take Benchmarks as the end-all to buying a processor. A CPU for this price and speed will do everything you want it to, unless you're rendering large 3D models or video editing professionally (but you shouldn't be looking in this price range, anyway). Potentially, you can get the support for this AM3+ socket now (as it will be the new AMD socket type for a few generations), and upgrade later when "Piledriver" releases or you have some extra cash for an upgrade. This is a "Bulldozer" AMD product, and has a 7.2 on the WEI (Windows Experience Index).

To note, this processor supports up to 1866mhz memory speeds without toying with OC'ing, but making it easier to OC the CPU compared to Phenoms (nothing against Phenoms, just relaying information). Albeit, I read that it will only do this with 2 sticks, but trying to fill all 4 busses puts strain on the memory controller anyway... so try to get maybe 8gb in 2 slots (2x4gb). This processor compares to Intel's i5-760, which is about $215 (1/16/2012).

Also, Windows was still behind on supporting FX processors when they were released for multi-threading.

what can i say. this CPU will blow you away. i have heard comments after comments that this CPU being such a disappointment. i just Upgraded over my AMD 955 and this baby is running my games 57-60 frames per second! thats with the power of the GTX 560 ti and 8GB if DDR3 RAM boys and gals. now when it comes to other performances sure the i7 and i5 are better and all that jazz. But when it comes to gaming or everyday computer needs WHO CARES! it dose just as good for 110 bucks! all u need. smooth game play, rarely any hiccups, cranked this bad boy from 3.6 to 4.O. cant say anything about the stock fan because i'm using liquid cool. and its actually not even hot while gaming or having two monitors compared to my 955. this baby is fast.If you choose a 6 core and your mind is set for gaming, your kinda wasting your money, because the AMD 4100 is a fast CPU and i personally wasn't expecting this to be that fast. Get it...stop reading this right now...just get it
