Hi all So, I currently have an iMac G5 from end 2005 - I think the final model just before the Intel switch and I love it but I do find it struggles a bit for performance. Actually I bought it for my wife and it's our first Mac and I would not consider moving back to Windows. But, like I said, I sometimes find things a bit sluggish and I'm often having to archive stuff off due to lack of disc space. I've have therefore liberated some funds to buy myself a new Mac and release the current iMac solely for the wife - she onmy surfs and emails so if I reinstall from scratch without all the garbage it will fly for that. The question is, what do I get for myself. I'm really thinking of a Mac Pro (hence the post in this part of the forum) because I want my machine to be blindingly quick. I'm not particularly doing anything intensive - OK, occassionally I'm rendering and burning DVD's but on the whole it's normal use - surfing, email, listening to iTunes, messenger etc. I'm also running SETI at home too. On top of this I do want to start using the new machine for music - I want to get a midi keyboard and start to compose and produce, this also led me to believe that a Mac Pro is the way to go as I can stash extra disk inside. I think I've made the decision to wait until the Mac Pro upgrade comes, maybe for Leopard too depending on the timing but then I'll be faced with the 2core, 4core decision as well. It's quite mind-boggling... Do 4 cores translate into faster performance etc. It's really not all that clear to me. Once I've decided this, then perhaps we can discuss what monitor to get I've read lots of threads but didn't see one that really gave me an answer. I guess the basic question is will a Mac Pro blow my socks off with performance?
