OK gentlemen, HD 4000 never more, ever.

Mine survived the voltmod (arround 1,36 V just quick look) with stock single-slot cooler just for like a three minutes. I just wanted to have a look at the temperatures before I change cooler and than the image turned off.

One colleauge's card did exactly the same (although he did not do the voltmod) so my opinion is clear - RV770 chips suck hard. My next card will be at least HD 5000 and under a short warranty at least, don't want to throw 40 bucks outta window again.
