I have been using a pentium 4 w/2.40 Ghz and 1gig of ram running XP Pro for over 3 years . I use PS CS2 and will be uprading to PS CS3 when it comes out. I am planing on getting Lightroom now that it is out. At some point, maybe this spring or summer, I was thinking of upgrading the system and getting a faster system w/duo core 2, Vista, availabilty of more ram and larger hd. I'm sure that this has been discussed before, but now that LR has been released, I'm getting more serious about what I might have to have "under the hood" as it were. As for a video card, I am only looking for photo editing purposes. Any recommendations as to what I should put on my shopping list? I don't know if I would build from scratch(my son-in-law want me to) or go with something from Dell or such, and just make modifications as I see fit.
