I have to agree with him there. I've been in the IT field for many years and Nvidia based cards fry a LOT more often than AMD/ATI Cards as far as I can remember back.
i remember seeing a lot of posts in tech forums about people having to "bake" dead 8800s (especially ones pushed hard in folding@home and such) to get the solder to reflow, bringing them back to life. worked quite often but was usually only temporary.
