Performance is excellent; the quad-core Intel Core i7-7700HQ is a great chip not only for gaming, but for video editing as well, while the GTX 1060 graphics hardware is more than good enough for the latest games at High settings in Full HD. Round that off with a bit of old-school design charm and an excellent keyboard, and you have a very attractive machine.
Another spec to watch for is panel type. You'll want to go for an in-plane switching (IPS) panel if possible, as they generally offer the best off-center viewing angles and colors. Some gamers are content with cheaper twisted nematic (TN) panels, which make you settle for narrower viewing angles—but then, you're probably seated directly in front of the screen, so that's not an issue. TN panels can offer slightly faster response times.
Dell Home, via its Member Purchase Program, offers its Dell 15.6" Laptop Gaming Backpack in Black/Red for $28.49 with free shipping. That's tied with our expired mention from four days ago as the lowest price we've seen for this bag. (It's the best deal we could find now by $20.) It accommodates laptops with up to 15.6" screens and features a shock-absorbent EVA molded front shield, adjustable shoulder straps, and a deployable rain cover.
