also to add, cad on 32 bit?, i mean heck the screen is way to small already, if i was runnin cad i would be on 64 bit with at least 6 like ubrales said, if even 4.., ive had to do stuff in cad at school a couple years ago, and we had 1gb or ram on the machines...not somthin that was really do able, the machines where always hanging and crashing, so we had to restart them at least every class period... so it would speed back up
