Why did my graying PC with Intel Pentium 4 (2.66 GHz) donated this 2GB memory, so that he even Windows 7 can experience with me and it works! Performance is ok for everyday use of internet, email and Office ... For gaming, it would probably not be enough, but perfect for everyday use! Even my cable Germany he creates 100,000 cable Flat loose with Windows 7. With XP is no longer and therefore also the transition that! I am very satisfied, the upgrade to 2GB of RAM was at the price more than OK, man does not always have to buy a new PC ...
