AMD 2200+ 1.8GHz processor. 512 mb ram 100 gig HD It has an intergrated video card, which is what I figure needs upgraded first. Has the empty slot in the motherboard for a card. I am not a big gamer or anything, but I do want some sort of audio/video in and out to watch movies/play music in my family room off the HD and capture vids off TV, etc. S-Video maybe? Not wanting to spend over $150 on the video card. Also, it has a 250W power supply, when does this need upgraded?
