Im considering picking up a couple of 680's but im curious as to how much heat, (in watts) these GPU's produce at stock. What im looking for is something similar to how Intel rates its chips. For example, the intel i7 990X is in the 130W category. What is the rated heat the 680 GPU's produce?

    Maximum TDP is arround 195w. Normal TDP under normal load is arround 160w.

    From page 3 of the review at guru3d :
     
    Max board power (TDP) 170 Watts

    What is normal load? less than 100%?
     
    At stock voltage and core clock speed, in benches with 100% load, what is its rated heat? 195W or 160W?

    the 680 dynamicly clocks up and down , volts up and volts down 
     
    you may want to consider average rather then maximum
     
    example) 2500k is rated at 95W mas tdp but after overclocking to 4.8 and running BOINC on all cores it doesnt reach that point ( very not default config. ) i ran my old 2500k @ 5ghz 1.52 volts it perduced 110 W @ load and it died after 3 months of that.... TDP is useful for life expectandancey  rather then anything else in my opinion

    I dont see how that makes sense.
     
    If your stock TDP is 95 W at stock clock and voltage of 1.2v. If you up your voltage to 1.52, that changes your TDP from 95W to 206W, not 110W. The reduced life expectancy was no doubt due to inadequate cooling if you tried to cool for 110W instead of 206W.
