He, someone I know wants to buy a used mac pro G5. It has a speed of 1,8 Ghz. I think he's going to use it for music. (logic pro, adium). But he said he was going to use FCS as well. His question was if he could replace the G5 singlecore chip, with a G5 dualcore chip. And if that's possible, could somebody give me extra info about compatibility and such. For example, will it just boot without problems when you replaced it, or do you need to do extra things (drivers, reinstalling the os and such). The G5 will be used in the near future for HD video editing. Also, I know the new intel mac pro have graphic cards from nvidia and ati. But what graphic cards do the G5 towers have? are they good? Thanks for the help.
