Yes, I'm looking at all the parts combined. The dock is roughly $200 and the GTX 970 is $350 right? Then I think my mistake is I though the laptop was $1500.
Yes the amplifier is a little under $200 and depends on the exact GTX 970 card ( most of them are below $330)... Now if you buy something for x price ( talking about machines) , as soon as you start using it, it's price starts to depreciate. So even if you think it is in excellent condition- you have started using the laptop so it means that it's battery power is reduced to an extent among other things. So you are looking at maybe a few hundred dollars of depreciation. (Another thing taken into consideration and that does affect resale price, is the lack of warranty)..
