Gaming seems to push the battery time to about one hour for such a machine. Can you share ANY machine that met your goals? I haven't found one yet so 5 hours of gaming makes this feel like another unicorn hunt.

Looking for a new laptop to replace my venerable (and very slow) 1525.
Need it for a combination of business (Office 2013) and games during downtime/travel.
Here's sort of my minimum:
i7 processor, 8 Gb of RAM, minimum of 750 Gb of storage. Nvidia discrete graphics processor for movies/gaming.
External battery and about 5 hours of battery life.
Either 14 or 15 inch screen.
Prefer Dell or Lenovo.
Already tried the Lenovo Edge 15 and returned it. Poor battery life and speakers were on the bottom of the case.
Thanks for any & all suggestions.
