4 gb of ram is so much. 8 GB is definitely overkill unless you are planning on doing something involving video. With ableton you would actually be fine with 1 or 2 gb, 4 gb is plenty.

If you're building a machine dedicated to photo of video editing, I recommend 8GB of RAM. If you want a fast PC, I recommend 8GB of RAM.
