Hi, I am looking into buying a powermac g5 dual 1.8, 1gb ram, 80gb hd, for $400 CDN. This is an extremely good deal. Its through kijiji. The seller said that I could hook up the computer to a monitor to test to see if it works properly. I will be using this macing to replace my dual 800 quicksilver, 1.5gb ram. I've herd that the 1.8 dual have a high failure rate. I did some googling and found that 23% of them have this problem with the logic board failing. I will be using this computer as my primary machine with dual monitors, so I want to know if it will last at least 2-3 more years. I asked the seller, and he said that the dvd drive was replaced under warranty, and there have been no problems with the logic board. I dont want the logic board to die on me in 2 years, so I want to know what you think. Do you think the computer will last 2-3 years or even more, or do you think the logic board will die before that? I will also MAYBE upgrade the video card, so post suggestions for a dual monitor video card as well. Thanks.
