Hello, I'm planning on buying an Alienware X51 R2 at the price of 370 euros with an i7 4770 and a crap gpu (gtx 670). Does that seem like a good deal? But, I have the money to buy a blower GTX 1070 Ti (yes, 330W does support this gpu when set to 80% power limit in msi afterburner). I really like the design and the compactness of this machine. But, should I buy a GTX 1080 Ti and the rest of the system (900 euros), or get this small beast (630 euros, including me selling the old GTX 670)?
