would the new rumored mac mini at 1.5Ghz with the 64mb video card and 1 gig of ram. run photoshop CS2 and a 23" apple display at a usable speed. I am currently using and 15"g4 powerbook at 1.25GHz with1.25gig of ram. I am not sure how fast my hard drive is or what video card is in it. I cannot afford the power workstation at two grand and I would like to free up my laptop for field editing of photos. the power book/display thing is slow but not completely painful. any help or suggestions.
