Value of used gaming laptop? (specs included)

[LogicMia]

17.3 inch Acer Aspire VN7-791G
CPU: i7-4720HQ @ 2.6GHz
GPU: Intel HD 4600 + GTX 960M
Memory: 16g RAM, 2TB HDD
Disk Drive

Definitely used, but still perfectly functional. I'm looking to offload this older gaming laptop and wondering about how much I can be expecting to realistically make off of it and perhaps get some suggestions on where I could be selling it?

Thanks in advance!

Considering that it is an older laptop, I wouldn't pay more than $500-600 for it. They are quality specs and would be worth more during its prime but considering its age it's hard to label it any higher.
