Some sort of resistor or diode.  I'd suggest taking it to an electronics repair place and getting them to estimate on it.  It'll be an easy job if it's just the surface mount component missing.

the graphics card is almost 7 years old, to get it fixed will probably cost half of what it’s worth. 

i’d say if it doesn’t work fine without it, replace it.
