based on many comments I've read here at [H] I found it interesting that 100% of the comments I read have been focused on the GPU. Gamers say they won't buy used mining cards on eBay, miners say the GPU's are under-volted and therefore actually used less than if it was used for gaming. What about the memory chips? - Do memory chips (GDDR5, etc) have a limited read/write spec ? - mining is number crunching. Is that hardest on the memory chips?
