Any experience with AVCHD files? (I don't have any)

I have it loaded and running NX5U( LPCM audio), SR11 and XR500 files in realtime. My Q9450 is not that fast by todays standards but will run multicam with 4 tracks with just a few complaints, 2 tracks work no problems. I am happy to use this way until I upgrade to a faster machine later in the year. Single or 2 tracks seem to work fine on my machine. Others with i7's are reporting much better performance on the GV forum

Yes it is nice. Now AVC files can be treated like any other file format. Just throw them on the timeline along with filters and edit away in realtime.
