I am going to get another computer. My present system is old and too slow. My wife works for HP and can get a discount. I've been looking at systems that can be configured to your on specifications but not exactly sure as what I should really get. Want to really get into 3D animation.

Any Suggestions as to what is a good processor size, graphics card, operating system and especially how much memory. Saw a system ton my wifes HP site that can have 24GB of memory. WOW!
