The Dell Inspiron 7577 is Dell’s previous generation top midrange gaming laptop and for this price it’s a steal. For around $670-$720 (depends on the configuration), this machine comes with an I5-7300HQ, an Nvidia GTX 1060 6GB Max-Q, 8GB DDR4 RAM, 1080p IPS display and Thunderbolt 3.
The GTX 1060 Max-Q performance (link) is almost as good as the non-Max-Q variants and is much better than the GTX 1050 Ti GPU (link), so it’s pretty good and you probably won’t get any better than that for $700 until next generation of GPUs from AMD or Nvidia. According to reviews, thermals are pretty good, with the CPU temperatures remaining under 70C even for highest load, chassis temperatures high mostly in the middle but not unlike other models, which is acceptable.
Equipped with a thunderbolt 3 and USB 3.1gen2, the connection ports selection of the 7577 is rather good.
Display quality is typical for current under $1000 gaming laptops selection, which means you get a basic IPS with low color palette coverage, limited brightness and ok contrast. No PWM is in use, which is good (no flickering).
Bottom line, if you can get it from Dell’s outlet in time, then that’s a good deal. Competition for $700 usually comes with a GTX 1050 Ti and a lot more extra features, if at all.
