First of all what is a "Quadro"????
Oh well....but from using different CAD stuff on different computers i think that for a computer with it you need a decent graphics card...at least 500 mhz and probably 256 MB of RAM...those would make everything run pretty good...other than rendering with 3d studio (havent done that much) but u might need even more to make it a some what speedy process...
P.S--> Also if u want to get something really cool for using CAD stuff get a "Space Ball" they are a really really really cool mouse thing that has a ball on it and you can move around 3d objects like nothing you've ever seen.
