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.
Here is my definitive guide to how much RAM you need. Note that dual-channel motherboards will support 1GB, 2GB, 4GB, 8GB, and 16GB of RAM, depending on motherboard, while triple-channel boards support 3GB, 6GB, 9GB, or 12GB,again, depending on motherboard support.
