lancef3113 - Just get yourself a 1 gig stick of RAM you can find them on newegg for $68-$85, and put that in your spare RAM slot, your mobo only supports 1.5 gigs max. You can also get yourself a good 4x agp video card for about $100 like the 6600le that would help out a lot. If so if you don't mind spending $200, shipping included, that would probably give you a good performance boost.
I personally would scrape together $1500 and build one so you can just get parts that would excel at video editing.
If you're a hardcore editor then use a mac, that's what the G5's are for. If you wanna stick with a PC get an intel dual core since you're not going to be doing any gaming. I like AMD myself but I have a Pentium D 820 that works just fine.
Make sure your RAM is at least DDR2-667 Corsair or OCZ, you can get their high end lines but I think the value lines will work as well. With mobos, a lot of people consider ASUS to be one of the best; ABit and Gigabyte are pretty solid as well.
As far as your video card goes, look into the ASUS Extreme N6600GT Silencer/HTD, cause that card can handle HDTV, or an All-in-Wonder card from ATi.
Get a big hard drive because you're gonna need it, at least 250 GB, or get a couple and set them up in RAID (if you got the cash, get 3 and use RAID5.)
