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.
Bill gates once said, ...256 KB..., but that was years ago! If you are using XP for best performance no less than 1 GB (2 if possible) of RAM (the more the merrier) and vista 2-3 GB. Also, take your OS into consideration. If you use a 32-bit, then the maximum is 3 - 3.5GB but I wouldn't recommend under 2. For a 64-bit OS, pretty much anything will work.
