Hi! I am a long time PC user and I have recently received a grant to purchase a computer. I'm unsure of purchasing the current line of the PowerMacs because of the subtle upgrade that was introduced last week. I fear that my hasty purchase will lead to a huge disappointment when the '970MP' is introduced to the public at WWDC. So my question is... Will the current line be upgradeable to the new processor once it is released? Will I be able to utilize the dual capacity of the system with two dual core chip making it a quad system (I don't know how the system will handle 4 'processors' when it was intended to handle 2)? I don't mind the other aspects of the system, since computers get slow from 'outdated' cpus and bus speed. Thanks in ADVANCE!
