Its been nearly 3 years since I bought my dual 1GHz G4 PowerMac (Quicksilver 1GB RAM, 80GB+20GB, SuperDrive, GF4MX 64MB), and it has served me well, and honestly still does do everything I need with adequate speed. But, its getting close to that time when I want a new Mac again! Now, I was gonna wait until next year and get a mid range or top of the range G5 PowerMac, but the G5 iMac has made me think twice about it. A G5 PowerMac would cost a small fortune, for power that I dont really use, but it would last longer. But then I just love the new iMacs form, the idea of just having that sitting on my desk (Im actually even thinking of the 20, even though I have bad mouthed the 20 in the past for being a waste of money in the G4 days) rather than having a huge bloody great tower to find a home for, with wires running to monitors etc seems so much nicer. Plus the fact I could get a 20 1.8GHz, with 1.25GB RAM, 160GB, SuperDrive etc for the same price as an entry level PM with no extras. The only thing making me hold back is wondering if I will notice a difference going from my dual 1GHz G4s, to a single 1.8GHz G5. Bear in mind, I really dont do anything to strain the dual CPUs at the moment (no 3D, video, heavy PS etc). So with this in mind do you think that a single 1.8GHz would appear faster for my needs (web, adium, occasional PS, iTunes etc)? Or, do you think Id still be better off with a G5 PowerMac? Why? Thanks for any input you can give!
