that was with a different program, with likely a different driver, so you're not really comparing apples and apples.

"a" was a valid point several years ago, but nowadays amd gpus are just as stable and reliable on linux as nvidia gpus. as for "b", no, nvidia is not as fast as amd on sha512 hashes. even with the 55% loss in 64-bit performance compared to previous generations, the R9 290X is twice as fast on sha512 as your Tesla at 1/5th the price.
