I have had AMD processors ever since my first PC back in 1998. They're not huge speed demons but when you factor in their cost (and the cost of the hardware that supports them) and their power usage they're brilliant.
I wanted to upgrade the processor for my (relatively old) motherboard, so it had to be an AMD and luckily my motherboard supported their CPUs all they way to a Phenom X4 970. But the Phenom had some issues with compatibility with AGP cards (yes, I still use those) especially on 64-bit systems, so I started to think about an Athlon II X4. It's still a quad-core with 45nm technology, but no L3 cache (which is what causes the issues). However, the Athlon was my previous processor and it is a proven and mature chip - probably getting old by now, but what matters to me is stability above all - and especially it came in much cheaper and with a lower power consumption (95W instead of 125, so less heat to deal with and cheaper electricity in the long run) than the Phenom X4. All in all it seemed a safer upgrade all round.
The CPU comes with a decent heatsink and fan (4-pin) and pre-applied thermal paste, so installation is straightforward.
Result? It's early days still, and I wasn't expecting a huge increase in speed (the motherboard's chipset and other components also affect your overall speed), and this is reflected in general 'desktop' use, but as soon as you deal with encoding or rendering - bang! Real quick! I could see a remarkable decrease in video rendering and encoding times, programs load faster, and all processor-intensive tasks go like a snap. But above all, I was able to deal with HD video more comfortably than with a dual-core CPU, which was ultimately my aim (I work with video).
Bottom line: if you're in a position similar to mine, with an old AM2+ motherboard and relatively old components, and not much money to spend, this is by all means the best way to spend your upgrade money. I did not buy it from Amazon in the end, and the price will fluctuate, but if you can get it for less than £100 you won't regret it - sorry for the pun.
Great speed advantage, especially over multimedia and processor-intensive tasks, low power usage, no technical issues and low cost. A great chip with oodles of speed and no serious drawbacks.
If you're looking for value and dependability, look no further.

This was a planned build of a new PC and having taken a lot of notice of review material, I settled on this CPU - the AMD Athlon X4 II 645 Quad Core, which received good reviews all across the board and was the best balance of proce and performance for my projected system - paired with an ASUS M4A88T-M motherboard
Quick service and keen price were further attractants.
I have a very good local computer supplier, but they were unable to match the price from Amazon.
So far, everything is working very well, and the speed increase over my previoous system is almost unbelievable.

It works great!

Amazon Verified Purchase
It worked so well, I upgraded to the Phenom II X6 1090T 3.2Ghz. I haven't built my own computer for years and the perfomance improvement from my old machine P4 3.1 was so drastic...the geek bug bit me! So I bought another motherboard GA-870A-USB3 (I'm a Gigabyte fan)and the 6 core AMD. If you can afford it...go six core! But for the whole week I had the quad...I was smilin. AMD is GREAT. I use my machine for film editing, and the speed increase was dramatic.

Great Deal
18 Nov 2011
Great CPU, I had a Athlon 7850 which was a 2.8GHz Dual-core Black Edition. The temps ranged from 40c-50c. After upgrading I notice not only the performance boost but my temps are as low as 23-30c, very rare that it reaches 32c.
My only con is that I orderred from Newegg, they were only selling the CPU but excluding the fan & heatsink. After tax the price is the same as here but you get everything.

Superb CPU
20 Oct 2011
I have been using this quad core since last one year now, and I am very happy with the performance. I use my PC for online gaming, watching movie videos, do my office work and lotsa other stuff. I got a decent graphic card as well, so overall the performance for gaming is awsm.
