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.
3 - 4GB. If you're running a 32-bit operating system then with 3 or 4GB of RAM installed you'll only be able to access around 3.2GB (this is because of memory addressing limitations). However, with a 64-bit operating system then you'll have full access to the whole 4GB. The difference in performance between a system with 2GB of RAM and one with 3 or 4GB is like night and day. Even on a 32-bit system that limits the RAM to a little over 3GB, the performance boost is well worth the cost.
