Performance improvement ?!
The is definitely noticeable even if I have to say that you get used to again to the increased speed of the computer.
Cheaper and more effective than a new processor / computer and it is always worth it, especially for users who need to run multiple programs simultaneously.
The product maintains an everything it promises. Processing and shipping was also very fast. (2 Days)
So I can only recommend the Arbeitsspeicherkit. Thumbs up!
