Vista X64 SP2 beta download/install went without a hitch (the 612MB). As yet the only thing I've had to update was the Auslogics Registry Defrag to the 5.0 free version. From the time I push the start button to the time the desktop is fully loaded is about 90 seconds. All seems to be running well. My G15 kb shows 25% of my ram being utilized at idle. So far have ran FC2 and TDU with no problems. Can't complain.
