Is there an estimate of how many points could a 6450 net? I'm going to upgrade the CCTV unit in a couple of months and I think I could put a 6450 in there and leave it crunching all day. Maybe even a 6570 if I get one cheap. It would have to be an XP machine (darn capture program won't work on W7) so it'll be limited to the 32bit client. Is there any impediment for this?
