No I'm not having issues Colin, but a friend is, and I am wondering if the
card is implicated considering these are new cards and presumably may not be
catered for in RC1. The installation appears to be ok until the pc reboots
and then 'blue screens'.
If you/your machine have the capability could you please try an installation
and check it?. You obviously do not have to stay with RC1 considering you
have concerns about running "a pre-release OS on it".
