Re: Dell New Inspiron 15 5000
@FionaRhianne That laptop should handle all Sims 4 packs together on medium-high settings, or maybe high if you didn't install all of the EPs or didn't mind somewhat lower framerates. (People have different preferences.) It's a good laptop for what it does; it's just not a gaming machine.
Just so you know, you could do significantly better on the hardware for the same price. This Lenovo has a stronger processor and a graphics card that would handle all Sims 4 content on ultra settings, although only barely:
There are a number of upgrades available, including getting a much faster graphics card (£50) and doubling the RAM to 16 GB (somehow free).
If you'd like to see other options as well, let me know.
