A few months ago I was in the same situation, although I wasn't as concerned about Windows Vista as I was building a computer that would last me through university and be "future proofed"... However for all intents and purposes I think that you should look into building your own. Do you know a little about computer hardware?If so...It took me about a month of reading a book on and off (between working 8 hours a day on weekends and school and homework on weekdays), to learn how to build a computer. It's really not all that difficult, and it can save you a lot of money...I built my computer for about $1800 Canadian, and a comparable (but a little worse) Dell would have cost me about $2300. Well worth it if you ask me. Basically I just saved myself $500 bucks by reading a 20 dollar book.Anyway, just a suggestion.As far as the PC you posted goes, it should be more than enough (if not a little overkill) to run Vista. I'm assuming that if you're buying 4 gigs of ram and 2 terabytes of storage, you're going to be running a LOT of programs at the same time, and have a lot of files/music etc. If not, then you should definitely consider economizing where you can afford to. One of the advantages of building yourself is that you get to pick and choose the high end components and economize where you don't really need to get the top of the line stuff. The downside is that each component has an individual warranty, unlike Dell (who pretty much covers everything), and you'd have to spend a good month researching everything.Hope that helps a bit...
