  • 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% .
