From an everyday usage point of view, the difference in processor performance is not a big deal since the performance difference is pretty small.
If you plan on playing games, then the Acer Aspire E5-573G-52G3 for $80 more will be worth it because it has a dedicated nVidia 940m GPU. That laptop also has a 1080p screen, but the 940m is not powerful enough to play most games at that resolution.
The Acer Aspire F5-571T-569T has a 1366x768 resolution screen and it uses Intel's HD 4400 graphics core which is pretty weak compared to the 940m.
