11.5 has an opencl integrated in it's software so you really don't need to download anything new.
Now cause your new I'll give you a hand.http://www.youtube.com/watch?v=-xoMK0OG81M
This is one of the best youtube video"s to get started.
also my code of the .bat file that you have to create I putted something extra wish increased my hash rate with 65Mh/s
start /DC:\poclbm poclbm.exe --frames 30 --worksize 256 -v -w128 --host=deepbit.net --port=8332 --user=yourusername --pass=yourpassword --device=0
This code works perfectly if you follow the youtube video.
