Ideas for new build

[rapperwith1p]

Hello everyone I need advice for a new custom pc. My laptop just died and although I'd to have another one I don't want to take the chances with laptops for a while. So here's what I use my computer for...lots of multi-tasking, lots of video stuff, burning, chatting, homework, music (some editing as well), and some general surfing on the net. I was under the impression that AMD processors are good for gamers but Intel has the right processors for everyday use and multi-tasking. I'd like to go dual core but am limiting myself to a $1500 or so budget. The actual PC would have to be around 1200-1300 since I'm looking to spend the rest on an LCD monitor. Thanks for any suggestions.
