I switched my FX-8150/2x 7770 rig over to BOINC Manager 7.0.42(x64) and added the app_config to it. It started right up with 8 wu's (4 on each card)
I used the file above that agent00skid posted (All I changed was the concurrent # of wu's running from 4 to 8).
Thanks to KieX for the heads up and agent00skid for posting a draft app_config to try out!
