Shown below is my Video editing system for some home use based on AMD and using the DV500+.
I Love the system, and feel it is easy to use and learn.
I originally tried the nforce chipset boards (both the MSI 420d and asus a7n266e) but both of them had a problem with the pci bus. I would recommend you at least consider a raid setup for the video data, because trying to copy a 10 GB file so you have a working file, and a backup is slower on a single drive. And putting the software on one drive and capturing to a clean raid data drive makes houskeeping (defragging, management) easier.
The DV500+ does require rendering to see the digital video transistions (only the fades/transitions render), but you don't have to render to see the transistions on an analog tv monitor.
I have had no problems with the pci latency deal eveyone references with via chipsets, but my board came with pci latency setting in bios. also I was very well schooled on settiing up inerrupts and disabling devices after working 3 weeks with both the nforce failures.
www.videoguys.com is a better reference than me.
good luck
