Hello guy's! Well, I have used PC's since 1994 and I'm seriously thinking of switching to Apple. Problem is, I'm not loaded and can't afford a £2k Mac Pro and TBH I have no need for that much power. I mainly use the PC for Lightroom/Photoshop, iTunes and the internet so I feel a Mac is better suited to this work. I'm looking at either a Dual 2GHz, 2.5GHz or 2.7GHz G5 PowerMac for under £1k. So two questions. 1: Will there be a noticeable difference from the 2Ghz to 2.7GHz for what I'll be doing? Leaning more to the 2.7 just because of the water cooling . 2: I realize these have AGP cards in them and everything is PEG now, so I'm wondering what is the best graphics card I can get for these suckers? Not that I'll do much gaming on it, but good 3D performance would be good. Also any tips when browsing to buy would be awesome too!
