A bud told me about these tests for my old card, after running the tests I saved the results and matched them up to my new card. The difference was amazing. Some of the elements of the tests wouldn't even run on my old card.
They are huge downloads but well worth it.
I didn't care to much for AquaMark but the other two were excellent
A side note, when you run the two from "Futuremark" they both have a scene with running water, I can only dream that the next edition of Flight Sim will look that good.
