From an article on makeuseof which addressed the question I had of how do I find a really good mid range laptop when mine went out last. I finally was handed a used one that I put an SSD drive into. I am now looking to upgrade the SSD drive for more space.
This article explains why is is so difficult to compare units, still the final two ACER units are a solid recommendation:
Acer Aspire E5-573G: As mentioned earlier, the E5-573G may use the slightly older Broadwell generation of CPU, but it’s paired with the NVIDIA GT-940M GPU and includes a 15.6″ 1080p screen, and 6GB of RAM. You won’t find a better performer anywhere for the money.

Intel Core i5-5200U 2.2 GHz (3 MB Cache)
Acer Aspire V3-572PG-767J: This laptop uses the 4th generation Haswell architecture, along with the unupdated GT-840M GPU. It’s a solid performer and for $533, you could do a lot worse. There haven’t been big performance increases with Intel’s 5th and 6th generation processors, except within their integrated GPUs and in battery life. However, this unit uses a discrete GPU, so there’s not a tremendous difference between this laptop and modern ones.
