huh its a resister on all reference boards that I have seen
The component is labeled 'C1180'. From my experience making PCBs and utilizing surface-mount devices, 'C'
normally always denotes a capacitor. In this case it is a surface-mount ceramic (most likely) capacitor.
looks like its on pin 4 or 5 witch would either make it a ground or a SMCLK/SMDAT there would be no reason for a resistor on any of those
I'm not a professional Electronics Engineer, but from the formal education on the subject that I have had, says that it could be a decoupling capacitor (if that's the correct terminology for this use) which is used to filter noise and prevent it from affecting the rest of the system. Essentially gives a cleaner clock (if that's what those PCIe lines are for).
EDIT: Actually having a look at the PCIe port, it appears to be on the opposite side of the key as to the pins you mentions, meaning it could in fact have been a bypass capacitor from supply to ground, which also is used to filter out noise/ripple from the circuit. This is more plausible as decoupling capacitors are normally closer to ICs.
This leads me to believe this card may have been in a system with a dodgy PSU or motherboard and/or was mistreated and suffered from terrible supply causing the caps to heat and fall off.
EDIT2: The repair? to those two caps (C59 and C62) circled towards the rear of the card is less than desirable.
