I agree with Geo, better to have this stuff out in public, not for his reasons though but to give me a good laugh.
When trying to show that the 512 GTX is a knee jerk stop gap product with limited life it is inadvisable to quote that nvidia has done it again and then list FX 5800, 5200U and GF3 ti500 as examples. I bought my Fx 5800 and GF3 ti500 many months past the intiial release date, in fact years. I bought my new GF3 ti500 in early 2005 for instance !
Also, another way of reading the MTBF graph shows that you have a 2% chance of failure in 4 years if you play 100 hours per week or 14 hours per day. And thats at 125C, the cards would reach 70-80 maybe, I'd like to know what the values are then .. maybe 2% in 100 years at 14 hours per day. Who knows ? 125C is a ridculous temp to give values at though IN THE REAL WORLD. Somebody has just taken lab figures out of context.
Actually out of context sums that up nicely so the PR/marketing guys are doing a good job.
I'm going to give this one 8 out of 10.
