Noooo, dont lower the RAM, it is ok..One i have seen mentioned alot is the Nvidia Quadro, this can range from $170.00 to $5300.00 (ish) it depends on the power you need. All are recommended for CAD use.
Most graphics cards just clip into a pci slot in the back of the pc, so changing the card isnt difficult. To find the best cards you are best visiting ptc's website, they have a list of recomended video cards.
Hope ive helped
