I have fried the northbridge chip on my motherboard. I can only find a dell 4600 motherboard on ebay, for too high of a price. I don't see any point in getting a new CPU, Motherboard, and case, since then my computer would not be that much better. I am considering getting a new iMac, because I need desk space, and it seems like a pretty good deal. OSX 10.4 seems alot better then Windoze, especially since it is based off of Unix. An iMac with Raedon x1600 GPU is only $1200. If I did get an iMac, the only thing I could upgrade is the ram. Is it worth getting an iMac, or should I just build my own computer (I wanted to build a computer for $900 using my old DVD burner, power supply, and video capture card.. My dad thinks that is too much money). Or, I will see if I can build a computer equal to the iMac for cheaper. Feel free to give me your opinion(s). Thanks.
