That's it. My second SN41G2 has just killed a second graphics card. Great.
My first one decided it was going to kill my 9700 pro which went all funny and started artifacting like something rotten.
I then ended up with another SN41G2 (cos I liked the case mods) and a 9800 pro. Now less than a month later the new 9800 pro has done EXACTLY the same thing and I can only put it down to my Shuttle being too hot.
Bah, back to the world of big heavy monsters I guess.
