I think the PC is well made, looks good and is by some settings very quickly ... In the beginning I found it very slow and also thought to myself that there must be something wrong, since he has a quad-core processor. After some searching on the PC I then found anything that Ennergieoption the processor is set between 5 and 100%, depending on how the PC retrieves the performance. This setting was not at my previous Laptop`s. You can adjust the Prozessorleistug! The PC will always be very energy efficient and uses also like to thank the 5%. Having the minimum power of 5 is set to 60% in battery mode, it was very fast, the battery life has not substantially reduced. If it is connected to the mains I asked him to minimum performance 70% and lo and behold, he was really fast. I do not need quad processor, when it is as slow as a processor 10 years ago, I've bought it because of the performance! I can recommend it with the new Ennergieeinstellung only further !!! Good value for Top ...
