Guys: My well worn laptop is getting replaced with what I consider a reasonably "stout"desktop before it quits at the worst possible time..I'm looking at a boxed Hp set, Amd quadcore; 7gb/640gb hd;vista home premium 64 bit; 2207h lcd. I do photo"work";web site building/maintenance; home business excel/ word, email and I'd like to get into video.. I keep and use my gear for 5-10 years.I'm looking at $900 for the whole thing with software.I could put components together for less but add in software and hassles and I'd rather buy turnkey.. Is the Amd quadcore a good idea? 64 bit premium vista a good idea.?I realize I won't be taxing all 4 processors. I want headroom for future innovations.
