My dear old dual 1.8 G5 is chugging along as good as ever, but ever since I received my MacBook, it really hasn't seen much use. The speeds are just worlds apart. To accompany my MacBook I'm looking in to 'upgrading' my desktop, to either a quad 2.5 G5 or a 2006 Mac Pro. PowerPC really does not hinder or affect my day to day use in any way whatsoever so the whole Intel vs PowerPC debate is irrelevant, it's purely a question of performance/value. Now the quad G5's are around £200 cheaper than the 1,1 Mac Pros, are the Pro's worth the extra cash?
