Would love some help on building my Pc (Do it with the webpage)

Why hello there

Im looking for a gamer pc with a price between 1000-1500 Sfr. (swiss francs)

I am planing on ordering it via https://www.digitec.ch/Startseite.aspx because we use the same contractor to order our Phones for our Shop. The phones are really beneficial so i tought the pcs might be some of the cheaper sort too, pricewise ofcourse.

On the page go to PC/Servers ->Pcs and from there on you can set the hardware.

I was thinking about geting the Alienware X51, Intel i7-2600, 8GB, 2TB, GTX 555, BD, Win 7 for 1349 Sfr but i think a part of the price is because it has written "alienware" on it.

I would love to get help, thanks.
