Will a 27" iMac C2D 3.06GHz 4670 suit my needs (upgrading from G5 1.6GHz PPC)

[Hellhammer]

Definitely! IMO the only advantage the iMac has over the Mac Pro I bought is a great huge big 27-inch screen, assuming the screen works ok! No, seriously though, the Mac Pro I got wasn't much more £££ than the i7 iMac, and with the iMac I'd have been restricted in terms of adding additional HDs, firewire devices, etc, so yes I'm glad I went for the Mac Pro. Funny thing is, I ruled out the MPs at the beginning because I thought I wouldn't have been able to afford one. In fact, 2 weeks before I pulled the trigger on that refurb I swear the same or almost identical model was in the refurb store with an extra £1000 on the price, so I think I got lucky . I also got lucky with the RAM.... 3 brand new sealed Crucial 2x1GB pairs for a total of £80.00 ...

WOW! That's great price for RAM! Anyway, great to hear that you are happy with it. I'm sure it is worth every penny you paid

I spent most of today installing Logic Studio.... 5 hours in total!......

Everything seems to be working ok......

I ran software updater and it found lots of updates for the software I just installed, so I downloaded the updates......

The updates installed fine, however now I have duplicate images in the Applications folder. The updated version (Logic Pro 9.1.1) is labelled 'Logic Pro' and the old version (Logic Pro 9.0.0) is labelled 'Logic Pro 9.0.0'. Is it standard practice for Snow Leopard to keep a copy of the previous version of an updated application in case the user wants to revert back? And should I leave this be or should I drag the old version to the trash?

You have the disks of Logic anyway? I would delete it, the same has happened to me with some Adobe apps and I've always trashed the old one.

Yeah I have all the Logic discs anyway. Is it just the file in the Applications folder I need to delete, or should I go hunting in the Library folder for other bits and pieces related to the old version?

The new Logic has likely replaced the old files so don't worry, just delete the app because if you accidentally remove something that the new Logic needs as well, you may have to reinstall it.

Oh, I know why it didn't replace it! 9.1 update made Logic 64-bit so if people are still using Mac/OS X that doesn't support it, it doesn't work so it didn't automatically delete the 9.0. Your Mac and OS X is capable of 64-bit so just trash it

Ah, makes sense now!...

Just a thought.... wouldn't I need to boot up in 64-bit mode for this, or does booting up in 64-bit serve a different purpose?

Even though 10.6 has 32-bit kernel as default, it is able to run 64-bit apps, just like Leopard (and maybe Tiger?). Booting in 64-bit mode isn't recommended because most drivers are still 32-bit so it may cause issues and it doesn't boost performance unless you use +32GB RAM.

One guy said it pretty good here. If you have 4 lane highway, but people only use two of them, what is the benefit from those extra two? Software isn't able to take much advantage of 64-bit kernel yet, they aren't enough "heavy" for it. The highway needs more traffic to benefit from those extra two lanes but so far, software isn't able to provide it

tiger isnt 64-bit, i dont believe it can run 64-bit applications either.

SL uses the 32-bit kernel by default but it indeed does have the ability to run 64-bit applications. the performance loss from this is negligible compared to using an actual 64-bit kernel, so i wouldnt worry about it.

i thought you only saw performance increase for >4GB RAM?

hmm im not sure that i agree with that statement that he provided. i would have compared it to a highway with ONE lane. for 32-bit single threaded applications/single core'd applications - there is one highway, and only one 32bit truck can run down it at the any time. same scenario for a 64-bit truck, but the 64-bit truck can hold twice as many trailers as the 32-bit truck.

a 32-bit single core'd multi threaded scenario is like having a 32-bit truck broken into maybe 4-bit smaller trucks, and sent down the 8 lane highway. etc

hmmm i donno lol.
