This will be my second build after many years and I am still learning. I am planning to overclock a little if at all because I don't know how to do it, but sure would like to learn. It will be used for gaming,music, and video editing. I have a collection of old cassettes with songs and I would like to convert them to mp3 and get rid of the noise. Would onboard audio work or should I get a sound card?If I need a sound card, which one should I get? Please take a look at the specs. The motherboard choices may sound expensive but I would like firewire and/or esata ports in back panel. I would like a quite pc in a roomier case. I don't care for the clear sides but do like the removable motherboard tray. I am not sure if my choice has that available What do you think about the heat sink? My budget is $1200 - $1500. I have XP professional and planning to use my viewsonic 19" monitor plus keyboard and mouse from an old computer. Please comment. Thanks in advance.
