How important is the ASIC rating on a GPU?

I believe that's for mining (computing). I don't think it matters much for gaming?

Found this little nugget of knowledge on the ol' interwebs...

TechPowerUp

Looks like it's for determining performance of the GPU... Possibly for OC'ability?

My understanding of ASIC is that its a arbitrary number chip manufacturers asign to different areas of the sheets the chips are cut from. They know that edge areas might be less pure for example and those chips need more voltage to get an oc or less oc possible.

Not sure anyone has actually shown that a 73% ASIC is harder to oc than a 90% ASIC but not alot of info leaking out of their labs.

My gtx 560 is ASIC of 73% and is shown in GPU-Z.   I don't oc cards so don't care much.   

Of course, I could be wrong.

Thanks everyone! I have been looking around on the internet too about it. It appears the higher the ASIC Quality the better clocking for a given voltage and lower heat for the same result when OCing on air.   Something to due with chip leakage or whatever and how GPU makers bin their chips for quality and how they will be used.

Over on the OC boards people are going nuts if they get a "low" ASIC and even RMA them. I was just curious since I just got into reading about it.

The real serious OCers even redo the BIOS and add parts or bypass them to modify their cards. Pretty obsessive I think but people sometimes are looking at hitting a higher number almost just for bragging rights compared to others.

Thanks again for the info and taking the time to respond. It is always nice to learn something new even if it doesn't change how I do things :-)

I even found this link http://users.csc.calpoly.edu/~clupo/media/GTXTitan.pdf about how to use the Titan as a development tool for CUDA and serious workstation stuff. By the way Nvidia has a development zone that you can go to and sign up and get software for development.

I know my Titan is overkill for my single 1920 x 1200 system but I have been playing around with Sandra benchmarks that use the double precision capability. Even downloaded Mathimathica trial just to mess around with it.
