upgrade memory, drive of 2007 iMac or buy new?
My hard drive is making lots of ominous noises — running often and roughly. I also seem to be taxing my 3 gb of RAM, as I'm gettting lots of spinning beach balls and delayed actions in programs. I have to repair permissions and restart daily.
Would it be worth it to replace the hard drive and upgrade to 6gb of RAM? That would run $200-$250, I gather from a quick search. Is it likely to give me another year or more on this machine, or should I start thinking about replacing it?
(I thought the disk was dying a year ago, but did a Diskwarrior repair, which seemed to help.)
