So what do you do with your old GPUs when you upgrade?

I'm not asking what you could do, but what do YOU do.

I sell them. I just sold my 280x and I'm saving up a bit more money for a Fury X

Sell them to soften the blow of the new GPU's price... I have 270X Toxic and I am looking to upgrade with 380 whenever I have the money. AMD is better choice for both my price point and my purposes...
