I'm thinking about replacing my hp pavilion 523n I live in a dusty house it's over a year old and it doesn't have enough operating capacity for all the junk I like to keep on it. I keep a lot of pictures for my job. I run Quick Books,Excel,Photo Shop and some LandScape design software pulse several other things. I know I want to upgrade to Windows Professional so what else do I need to know if I go shopping in the morning? I can afford to spend about a grand or so on just the tower. I wish I could build it myself but I don't think I'm ready for that yet. \nSuggestions please. Thanks.
