I have a question, currently i have a mac mini 1.42 with a gig of ram in it. But i of course want more power. so iam looking at the powermacs... but i wondering if i should get a Dp 2.0 or a single 1.8. i dont do any graphic work but i do encode avi's and mp3's would the DP 2.0 make a noticable diffrence?
