Hi I have a few questions about upgrading a power mac G5. So first off I have a early dual G5 and I was wondering if I could upgrade the processors to 2 dual core G5s. Then for my next question I also have a late 2005 G5 with a single G5 dual core and I was wondering if I could get a new dual motherboard with 2 quad core G5s and get a water cooler for it. Thanks for any help!
