Need help with a question?

I built myself a cpu about a yr ago when i was into gaming a put together a AMD 2400+ with a ASUS a7n8x-e deluxe board and 512 of dual ddr pc 3200, know that i don't do much gaming know that i have a ps2 i have been doing a lot with my camcorder doing audio and video extracting, capturing, and encoding, i want to speed things up but i have looked at going amd64 3500+ with a new board but can't afford it right know, so what would be somebodys suggestion but 2 120gb sata drives at 109 a piece and raid 0 them or purchase a 1gb kit of pc 3200 memory, or should i just wait till i can rebuild a media pc with a 64 processor, or the other question would be should i go intel since i have heard that intel is better with media and amd is better with gaming, any help would be great

Thanks Tony
