I have a iMac5,1 model machine,

Intel Core 2 Duo, 2 GHz,



When I bought it, it had OS X 10.4 installed, but my harddrive got replaced after a failure, the new drive had 10.5 installed. I've been using that ever since.


Since more and more software is becoming unavailable for 10.5, with no options of using older versions, I have been looking into getting a new machine, but not really able to afford one, the alternative is to update the OS to 10.6. I see it requires 1 GB RAM, so it should run fine on this machine, but as once I go for this option, there is no way back (I don't have a 10.5 install disc), I wanted to be sure it would run and not cause a decrease in performance.


I am using my machine to record screencasts, for higher performance software, that just about works. Any noticeable decrease in performance would mean I wouldn't be able to get the same quality work anymore.


Also, is there anything else I should be aware of when updating? Do I need to wipe my drive first, or does the install delete the old OS, install the new and leave all Applications and other files as they are?


Thanks in advance

iMac, Mac OS X (10.5.8)
