Ultimately the decision is up to you. If you don't need it right away, do what thuned suggests-- buy the dell. If you like it and don't have problems with it, that's great-- you've saved $427. Stress test it; run prime95, open a lot of programs while playing dvds, movies.. if it holds up without blue screening and you don't mind the lesser build quality, you're all set. If not, try out the T series.
