Well it depends because there will be loads of used 5850s on eBay after all the miners have quit in a hypothetical scenario and the market would be saturated ( where as now these cards are rarities ) and you could end up with nobody wanting to buy your cards or if at all, for a very small sum etc.
Of course the rest of the components are quite mainstream so i guess you could sell those but the min you take them out of the box the price depreciates etc.

In fact, most investors bought up 5xxx series cards, which really excel at mining but aren't really top end gaming cards. So now you have a market flooded with mid ranged gaming cards that most gamers probably already have or have better than, reducing value even more.

uh...says who? 5870s and 5850s, hell, even 5770s are pretty damn good graphics cards that can play most games out there without a sweat.
