I bought the EVGA 260 GTX Core 216 and I am about to get an aircooler or waterblock for it. I have read that some of these cards are 55nm and some are 65nm and the PCB's have different heatsink mounting holes. How do I tell which card I have?

GPU-Z will give you that information.

Do you have a pic of the back of your card?
