BACKGROUND Hey everyone. I am a proud owner of a late 2008 aluminium MacBook. I bought it only a few months ago at a fantastic price & have/do enjoy using it on a daily basis - usually hooked up to my 20" Cinema Display. I was offered nearly double the money I paid for it (£450) yesterday & am finding it hard to resist. My 'secondary' machine is a little Min-ITX Core 2 Duo system with a 6570 that I do all my gaming on. It's a nice little machine for what it is & has run every game I've tested on it, but it's no powerhouse. OPTION #1: MAC PRO I could take the money from the MacBook, sell the Mini-ITX system (minus the 6570 - which has plug & play support in Lion+) & buy a pretty spec'd up 2006/7 Mac Pro & a couple of hard drives. This would be an absolute beast of a system & would also double up as a gaming rig. In this situation though I'd be without a laptop (for the time being anyway). OPTION #2: QUAD G5 & POWERBOOK G4 Although the Pro would be the sensible option in terms of practicality & support & my head is screaming ''go with the Pro!''... The PowerPC machines are crying out to me. There's just something special about them, they have this amazing character that the (4) Intel Macs I've owned just lack. And I believe it's a much better situation to be in if you have a couple of slower, older machines that you really enjoy using than if you have one faster, newer machine that you don't enjoy as much. In this situation I would sell the MacBook, but keep the Mini-ITX PC, and buy myself a spec'd up quad G5 & a spec'd up PowerBook G4. To add to this notion - I'm not a massive fan of OS X past Snow Leopard anyway so the 'features' found in Lion or Mountain Lion would not be of any use to me. Having been a PowerPC user up until only November I am fully aware of the limitations of buying a 7 year old machine & am fully aware of the workarounds I'd have to undergo. What are your thoughts? I'd especially like current quad owners' opinions on their machine & how it performs up against something like an early Mac Pro. Thanks!
