Snapshot dependencies question

What i would like to create is a something that compiles project, and the compiled project, i would like to xcopy.

I was thinking the following teamcity setup

Configuration

1. build configuration which compiles the stuff

2. another build configurations xcopies what is build in a previous build. (i would not like to rebuild again)

I use promote to select a specific branch from build and xcopy it. It is a build chain.

Is snapshot suitable for this setup? Or do you have to use an artifact dependency required, because in this case you use the output of a build.

After reading the docs i am still confused.

Can someone help me?
