Its time for an upgrade from my 4 year old HP, I was thinking about maybe building me a new one this time. I'm going to use it for playing games mostly, and of course day to day surfing/average home user stuff. I will also probably use it for some light video editing. I have a 2.8ghz p4 sitting in a broken computer that got struck by lightning that i could use as a processor, although I was looking at AMD chips. Anyone got any suggestions? Budget is anywhere from $500-$1000.
