I've got a spare Nvidia M3000M GPU for sale after I switched out for AMD on one of my linux slabs. Used gently for gaming, machine learning, and Blender.

Works perfectly in a number of 17 inch laptops which include:
HP 8770w, 8760w
Dell M6700, M6800
Various MSI and Alienware gaming laptops
Does not work in the Dell M6600.
Rough equivalent to this mobile GPU would be a desktop GTX 950/ RX 560. Plenty of power for on the go.
Price is firm, below current market value.
