All this should cost about $975 - $1270 usd according to pricegrabber and I´m still missing the case and the dvd burner. I use my computer mostly for using autocad, photoshop, sketchup and other graphic editing, also watching movies, listening music and playing some games, mostly strategy like Civilization and the like.

What do you guy think about this mix?
