I have a G3 iMac GDV 400 that I upgraded to OS 9.1, and I upgraded the RAM to 2 sticks of 512 mb last weekend. When I asked here before, I was told to put OS 10.4.11 on it. Right now I have OS 10.3 in the house. Would it be OK to put that on it, and then look around for the disks to upgrade to 10.4.11, or would that take up more memory than going straight to Tiger? I'd like to be able to use it soon. TIA.
