So I finally have the money together to build my first pc. My budget is capped at around 2500. First I looked into monitors and settled on the samsung t240. I think i'll also want to have my old monitor (19" dell lcd) hooked up to for the hell of it. The only other part I know I need is a TV tuner. Other than that I'm open to suggestion and advice. I''ll primarily be using the computer for gaming at 1920*1200, watching hd tv and movies, AutoCAD, and other miscellaneous programs. So where should I begin?
