Hello folks, I recently bought a dual core g5 2.3 GHz / 5gb ram and 250 GB HD and I'm really enjoying the ppc experience. I'm not doing anything exotic with it - browsing/ e-mail/minor editing. My question is that I've spotted a quad core with similar specs for about the same money. Given I only paid around £50 I can probably easily sell the DC . My question is whether there any real benefit to the QC. I'm just interested because of the engineering and having a liquid cooled machine. In terms of day to say usage, reliability, power usage is there any marked difference? I guess this may boil down to opinions but that's what forums are for.
