BGA only??, is it true?

So i'm being offered an alienware 17 r3 as a replacement for my m17 r4 2012 model by dell.

And after looking around i've been reading about all these BGA (permanently soldered) CPUs and GPUs and how they completely suck performance wise.

Is it true that both are soldered or just one of them?, and does the soldering affect the performance of either or is it just a "no more upgrading" issue??
