I would think the 2nd hand profitability goes down in large drops each time a new series of card comes out rather than progressively, so keep your 7xxx cards till just before the 8xxx cards come out.
At what difficulty does a 7850 become not worth mining assuming free electricity?
When you consider with each passing week the value of your 7850 on ebay decreases by what? A dollar?
Right now a 7850 might fetch $120 on ebay. In a year you might get $70.

Right now there is a big glut of miners selling on ebay and this is driving price unusually low. This will end and prices on some cards (mostly 5xxx series) may actually go up a little.
If the price of BTC rises to $150+ or litecoin rises independently you will see used video cards rise in value.
Well, I currently get 285 Mhash/sec, so your 310 is pretty close to what I get.
I'm currently making 6 mBTC a day, and it's slowly dropping. At 100$, that's 0.60$ a day. So... Technically, assuming free electricity, even if you only get 0.0000001 coins, it's still profitable, because you are getting something out of "nothing". However, I'm stopping soon, (maybe 1 or 2 more difficulty increases) because I've just passed the beak even point. It takes me $0.67 a day in power to run my rig, and I'm now less then that on the coins I'm making, so I'm going to stop. Maybe once I drop below $0.40 a day, or even $0.50.
I don't understand your question about the graphics card depreciation...

He wants to know the sweet spot for when to sell his gfx card.
Presuming you bag roughly .006 btc per day with a 10% drop in earnings every 11 days the "talking out of my ass" value says to sell it in 8 months

Anyone good at math can punch in the numbers?
