Looking for a desktop to use for AutoCad,3dMax,and to play Sims3 on. Here is what I found so far but I am not sure if the graphics are good enough Asus Essentio CG5270-BP004 and Dell's Studio XPS 8000 (which I can customize). I want to get the best for my money because I still need a monitor and don't want to spend over $1,000 altogether. What are your opions or what do you suggest?
