Here's what I do to get the best option for my customers....go here
here scroll down and type in what games you want to test the machine on...it will tell you how it will do.
I tested that laptop on Crysis 3 and Farcry 4 at 1080p and it gave it Gold ratings...meaning it would play them on High or better settings.
$600 for a laptop that plays Crysis 3 on high sounds like a good deal to me....only issue I might have is Acer is not known for their batteries...short battery life is something that has plagued them for a while now.
