From a purely performance-technically I would clearly pick up the G20. However, I prefer to stay in my tower. wenns comes to upgrading you look with sonem participate safely in the tube. In addition, you will be in this cooling solution well when overclocking no real potential of the hardware can aureizen since apparently incorporated graphics unit as a reference design and the CPU also can not be really good cooled wenns goes to overclock.
the Report refers mainly to the built-gpu. a reference design that comes directly from NVIDIA is usually a map of other manufacturers and partners of NVIDIA inferior because it comes only with a stock clock and a cooling solution has is not just lautstärkearm. If you look, for example, once the different variants of the GTX 980/970 on you will notice that it, although they are the same chip, it is used mostly but better. which is especially the modified fan design of cards from different manufacturers. the cool usually better and are especially quieter than the reference design and provide for much better overclocking possibilities. Who is not interested, however, in good hands here.
for the CPU, the same applies. a stock cooler is usually worse than a modded cooler such as aero cool or corsair. heat can be dissipated more and above all you need to have no fear that it is too loud, because the fans are usually larger and may affect less rotations compensate more heat.
you could tell ... I get stuck at the long cooling but I think this is also important. in the housing sit up little space and there is Ekin airflow. the hardware is certainly faster hot and can therefore also possible white lower clock rates when it is too hot. which then in turn consumed on the power. it is cooling important so please excuse if I talk so long about the bush ^^
the price I would not at all starting out .... with approximately 2,000 Euro, the variant shown is just too expensive. you try a PC in console format to sell is far too expensive (my PC has me 1300 euros tasted with the same hardware). However, all the advantages of a PC go over the console lost wenns for cooling, overclocking comes and upgrade options. So why would someone for a bit less volume so spend a lot more money? I can only advise even if it is good hardware and the box brings a lot of power. good value for me when something important. and if the box is really so low I dare at referenzdesing the GPU and laptop cooling solution for the CPU also doubtful ^^
but as always, you decide what you buy.
So either resorts to cheaper solution or buys you these höllembox, I do not care.
but perhaps was it a good food for thought for many. In this sense, further gamble)
