multi gpu support

Hi

I see at the moment the latest AMD drivers for my cards are

  • (Radeon Software Crimson ReLive Edition 17.7.2 Driver Version 17.30.1041 (Windows Driver Store Version 22.19.662.4

and

  • (Radeon Software Crimson ReLive Edition 17.9.2 Driver Version 17.30.1091 (Windows Driver Store Version 22.19

?Do these support more than  8 GPUs on windows

(if not when is driver supporting more than 8 gpus going to come out)

?What's the max GPU's supported by each driver
