best linux distro

What ever package is capable to do that. It is a matter about flavor I believe. If you want to try good one, try Fedora (I believe it is the most stable - less copyright infringement distro ever build). Choose the right version, I mean if your processor have 64-bit capabilities, download the one that can maximize your processor. It can be use full if you need to do so much pushing calculating powers. Well happy linuxing...

try edubuntu or ubuntu and install engineering CAD software in it!!
