but I HIGHLY suspect that all 5xxx cards are faster on 2.1 SDK
I will test and report back when I get my 5850
I've got an increase using between driver 11.6-11.8 and latest guiminer, increase was from 314mhash/s to 320 mhash/s on my first, 316 to 322-323 mhash/s on my second card that just mines. Coming from 10.11 & 2.1 sdk.
two 5830's.
