Litecoin Mining – Radeon R9 280X hardware comparison

A lot of the magic in Litecoin mining is finding the best combination of hardware and cgminer sweet spot. I have done testing on most R9 280X GPUs and for easy reference, i would list the hashrate with link to tutorials on configuration for each of the card. This list would be updated from time to time when i obtain more cards to tweak. At the moment, it will mostly consist of R9 280X cards.
