Welcome to lockon.
Dont know tto much about the cyborg stick, but I had the microsoft precision pro is very good. if you really get good, you will want a HOTAS stick like the X52 of Cogar. TrackIR is also nice, but that and the HOTAS are a ways down the road.
As for you system specs, you should have no problem at all runnig lockon. (especially with that uber graphics card!) there are a few complications with vista, but nothing too difficult to figure out. if you need help, feel freeto come back to these forums.
