Go with the Dell. Both have i7's and identical specs EXCEPT for the dell having a GeForce 630M 1gb graphics card that the HP doesn't seem to sport. Much better.

Inspirons were and are shipped with a HIGH multitude of components. A 17R can have anything from Intel Graphics to nVidia to AMD. You'd have to have the Service Tag off the bottom to know exactly what is has on Dell's support site.
Case in point, my 1525 (CPXSNF1) had about 15 different hardware configs, all 1525s. The support page by Service Tag has original hardware, and tailors the drivers to that EXACT tag...
Okee dokee, but if they don't advertise it, its hard to know that. I usually would go with an HP laptop over a Dell any day. But how much more is he going to pay for that?
