Jeff,
Editing HDV requires a husky computer, for sure. If price is no object, look into dual core dual processor systems. However, you can build a very respectable system with a single dual core processor.
I recommend building the system around an Intel Core2 Duo processor, or an Athlon 64 fx dual core 4800+ or better. Use a motherboard designed for the processor, of course. Use 2GB or more of RAM, and follow your motherboard manufacturer’s recommendation on RAM brands and models. The RAM makers’ sites also have good info on compatibility; I like Samsug or Crucial. You can save a bit on the video display card…try getting an NVIDIA GeForce or ATI Radeon card, one or two models down from whatever the current top of the line is. I like the new PCI-E models. Get a good SATA or IDE system drive, and build a RAID 0 array from several identical drives for your video data storage. I have a 1.2TB array made of four 300 GB SATA drives; my motherboard has an onboard RAID controller and ports for them all. Make sure your power supply is man enough for the job…450 watts or better. I like the Seasonic models; they’re quiet and deliver clean reliable power. Get a good cooler for your processor.
Don’t install games, or anything else you don’t need for video editing on the computer. Don’t hook up to the internet, or a network. Or, if you must, set up a dual-boot system with one configuration optimized for best performance. Videoguys, https://www.videoguys.com, has some good suggestions for “tweaking” your PC.
If you’re intimidated by the idea of getting all these components to work together, or tweaking your computer’s registry and services for best performance, consider using a systems integrator. Find someone who has experience building computers for video editing. You won’t pay much more than for the individual components, and you’ll save a lot of time and agravation.
