I'm going to buy a new computer...photo editing will be my main focus...video editing and gaming won't be too high on the list...so I shouldn't need top of the line performance. Any suggestions or warnings? I'm thinking a Pentium 4 processor but what about other processors? Should I go with duel core or not? Should I spend more and get 3 or more GHtz...or should I save a bundle and get a 2.2 or 2.4? I've been looking at Dell.ca but I'm not seeing any better deals than what I've seen at Staples or Costco. Any advice would be appreciated.
