To my untrained eye, the Studio 17 looks better because of the screen (recall that the Studio xps 1647 no longer ships with RGB Led)

I also don't play videogames, so the slightly reduced gpu doesn't bother me at all.

 

Looking at the specs of both, looks like a fair swap to me. Upgraded processor, loads more storage. If I were in that situation, I'd probably give them the go ahead.
