Oh I know you were and I forgot to include that in there.
Video card would probably only see real benefits in video editing. Running your photo applications would take more ram than video I think.
So this would replace an existing machine or add to your studio? I"m thinking you said that you have a macbook pro and that's it?
If so, then yeah, a new one would be the way to go.
If you are replacing a mac in your studio, is there anyway you can live off of it for 6 months to a year? Wait until the next one comes out then get this one as a refurb/closing out?
