[SOLVED] What to do with old graphics card?

[hotelgolfwhisky]

Hi folks,
Got a shiny new XFX Radeon RX 580 GTS XXX 8GB graphic card arriving later today to replace an old faithful Sapphire Radeon R9 270X 4GB.
Question is, what should I do with the old card? I've got a secondary slot I can pop it into on the motherboard but I'm doubting the two cards will play together for any crossfire advantage so is there any benefit to still having it in the machine at all?? Probably wont help the airflow and cooling to the 580 for that matter.

Any suggestions??
Cheers

clean it up and sell it. Or maybe save it for backup.

Ok thanks.
Not sure a card from 2014 will get much value though.
In the back of a cupboard it is!
