The 7600GT comes in 80nm?

I went onto Wiki a little ago and looked at the long lists of GeForce cards, particularly series 6 and 7, and I came across the 7600GT, a card I'm considering of using for now because of it's good price (~$100), awesome power for a mainstream card, and low power consumption. One thing I noticed was that there was a 90nm fab version and an 80nm fab version. However, when I try to search for the 80nm fab version on Google or through stores, I come up with little to no results. And the results I do come up with always seem to have something to do with the company Sparkle.

Does anyone know if this new 80nm fab overtook the 90nm fab as soon as it came out? Or is Sparkle the only company distributing it? What's going on here?

Can't really answer the question, but why not pick up this 2600XT card if your budget is $100? It's faster than the 7600GT, has low power consumption, has better image quality, and DX10 and HDCP support.
