Amanda I bought an Intel iMac 17" 1.83Ghz when the first came out and it came with 512MB of RAM (running Tiger), the jump to 1GB made a massive improvement. The move from 1GB to 2GB was also noticeable. I would recommend upping from 1GB to 2GB especially under Leopard.
Intel Macs can run Tiger, but you need an Intel version of Tiger. A Leopard DVD will install on either PowerPC or Intel machine. Tiger however requires specific discs depending on the architecture you are using. All retail versions of Tiger prior to 10.4.4 were PowerPC only. After 10.4.4 you can install them on either architecture (someone correct me if I am wrong). Intel Macs use APM as a partition scheme but Intel use GUID as a partitioning scheme. Therefore a Tiger/Leopard installation from a PowerPC Mac will not boot an Intel Mac and visa versa. If you require Tiger on an external, I suggest you find a retail version of Tiger which is higher than 10.4.4 and install it on an external drive with GUID partitioning.
