What customers say about "Details"

AMD FX-8120 CPU Processor

Good CPU. I have a working motherboard for socket AM3 then just go for it.
Installed this, turned on my computer and started transferring files. Great and easy.
Easy to install. The AM3 + connector fit perfectly. Thanks AMD for the processor.
No bent pins and as with any cpu very easy to install.
Installed without a problem. Overall, very happy with purchase and would recommend.

Intel Core i7-3770K CPU Processor

Great product. It consumes less than 2011 socket units.
It`s very pleasing to me it that for once, Intel kept the same socket.
Installation was simple and easy, and pin alignment with socket was well marked.
As good as I can expect from the socket. Very pleased with the performance.
Actually installing was tricky. Aligning the pins to the sockets on the motherboard without bending the pins.

What customers say about "Technical Specifications"

AMD FX-8120 CPU Processor

This CPU thing handles 84GB data transfer like its taking 10GB. Very fast!
This is a great chip and I am very happy with my upgrade. 8 cores are super.
This processor is great with speed to handle even the newest games.
Many people run 4GHz+ regularly without issue but I have seen zero issues at the current rate.
I've modestly upped it to 3.4 ghz so it can run at effectively the same speed as the FX 8150, and it's good so far.

Intel Core i7-3770K CPU Processor

I have not overclocked it but on stock speed it is great.
This unit does a very good job in responding to my orders. I love it.
The speed is amazing working with 32GB of RAM and a 240GB SSD.
Teamed with my 245GB SSD hard drive and 16GB 1600MHz RAM, I can barely keep up with my computer.
Its actually too dang fast!. I'm not accustomed to this much speed and computing power.

What customers say about "Cache And Memory Specifications"

AMD FX-8120 CPU Processor

The cache in this chip really helps with performance. Definitely a great cpu for the price!
I found that downloading large files seems quicker, probably due to the faster and more efficient memory.
I got this with a new motherboard and 32GB of memory. Works perfect.
Everything I do on the PC (a lot of photo and video editing) is much faster now. Great L3 cache.
The only possible negative is that the 8 cores appear to share four sets of cache, 2 cores for each.

Intel Core i7-3770K CPU Processor

Processor with 8 MB cache works well in my rig. I highly recommend it.
8 MB L3 Cache is really good. The CPU does all my tasks.
This is a great chip. It's very fast, very stable, and the cache is pretty sweet.
I haven't yet seen a single memory hiccup. Works great.
By far the best processor. New DDR3 memory boosted my frame rates by about 25%-50% .
