For the Ethereum mining, the slow CPU will slow up the creating of the DAG and allocating memory initially. During the mining, it does not matter.

not always right, if you open too many instances with a weak cpu it may slow down your hashing on the gpu, try to do this with etheruem you will see the result
also some coin require the cpu to be free from usage, if it is a weak cpu, with a strong cpu you can use it to mine something else, while you do gpu mining

Also depends on if your are running a wallet for the coin. Depending on the coin that can take some CPU as well. There is always bandwidth on your internet but it shouldn't be that much unless you have a really slow connection.

Will a 2006 era computer with a pentium dualcore and 3gb of ddr2 bottleneck an r9 380 for mining any type of altcoin?

It depends on the coin's algo and its requirements. Some algos are memory bound meaning they require more
memory than the GPU has available and it has to start transferring large amounts of data back and forth between
the CPU & GPU.

On the CPU side you should only run into problems if you have a multi card rig with a small CPU. I like the CPU to
have as many cores as miner threads (one thread per GPU card) and, at least, as much memory as the total of all the GPUs.
In your case if your GPU has 3 GB of memory, or more, you could have a problem.
