HI, yes i've been eyeing up a T9300
the sticker underneath states "08/03" so i assume this is March 2008....... is that bad then?
There is enough information and misinformation on this subject to write an entire encyclopedia on the subject, so as briefly as possible I'll just say that the 2007 era chip had a flaw, only a very small minority have actually failed, but when one fails it virtually takes the entire board with it. nVidia did redesign the chip to fix the problem, but didn't do so openly, so there is no way to sort a good vs bad chip by looking at them. What we do know as "fact" is Lenovo replaced all their boards in production back in July 2008, so if your laptop is dated after that (08/08), then you have the updated gpu. Prior dates could have either, but there is much debate over that and no way to know for sure, however I can tell you that the failure rate sharply dropped after about febuary 2008, then the failures seem to have completely stopped starting in august 2008, so this is consistent with what we know and leads me to believe that units build in the 08/04 to 08/07 have less likely chances of failure.
As for the T9300, it's definitely the best all around option, but the T8100 and T8300 chips are also very good, and much cheaper.
