I currently have an Athlon XP 3200 running at 2.21ghz with a gig of ram. I have 2 Seagate 7200.10 HDDs in there. I'm having lots of problems at the moment. I record music and will be making my own site and doing graphics etc soon. My PC is just too unreliable. I was going to buy a Mac Pro on credit but think I'd be best saving up and maybe buying a Powermac G5 from eBay to last me till I save up for a Mac Pro that will last me a long time. I've seen G5s go for £500 on eBay. I don't really understand the CPU specs of a mac. Dual Core, Dual CPU (same thing?) etc means nothing to me. I realise the lowest G5 specs if 1.8ghz. How does this compare to my 2.21ghz PC? I do stuff that is CPU intensive recording wise. Is a dual 1.8 essentialy 3.6ghz? Would a 1.8ghz G5 be a step down (in terms of power and speed) from my Athlon 2.21ghz? I will be putting in my Seagates into the G5 and also my PCI audio card. What I plan to do is use this G5 as a media centre once I get a Mac Pro in the future so would like to connect it to a flatscreen in future. Any info I should be aware of? Thanks in advance. I'm really looking forward to moving to a mac.
