I just sold my MP 3,1, and was planning on replacing it with the current Mac Mini (i7 2,6GHz). But... I´ve a GTX 570 (-edition), and a Sonnet Tempo Pro 6G laying here, which is almost impossible to sell. Got a few bids, but the price were ridiculous low, so I decided to keep the items. I also kept my two HP 23xi screen So, right now a used MP seems to be a good choice. Thinking 4,1 8-core 2,26GHz, or single 2,66. With the 2,66 I could do the 5,1 hack, and replace the CPU with a W3680... The price is nearly the same. Which one to choose? To be honest, I really don´t need a MP, but I love the design. Right now my MBP, is powerful enough for what I do with it. Internet, mail, PhotoShop, Lightroom and Aperure is what I use the most. Editing pictures from my Nikon D300. I´m no hurry. Might be around christmas before I make the buy. And, btw, the new MP is out of the question due to price - plus I don´t like the design.
