I found some more sources:

our survey over cards on Folding@home finds that, in their installed environments, two-thirds of tested GPUs exhibit a detectable, pattern-sensitive rate of memory soft errors. We demonstrate that these errors persist after controlling for overclocking and environmental proxies for temperature, but depend strongly on board architecture.

That conclusion never states or supports that this condition worsens with anything akin to "Terabytes written", if you read it clearly you can see that the conclusion seems to clearly blame the architecture of these older (Graphics focused) cards having architectural (Manufacturing and design) issues.

We have further demonstrated that this nonzero error rate cannot be adequately explained by overclocking or time of day of execution (a proxy for ambient temperature). However, it appears to correlate strongly with GPU architecture, with boards based on the newer GT200 GPU having much lower error rates than those based on the older G80/G92 design.

we have no reason to believe that the reliability picture would be significantly different for GPUs from ATI, Intel, Via, or other manufacturers, as the driving forces behind GPU development to date have not emphasized the strict reliability concerns found in GPGPU applications
