Hello, I'm totally new to BitCoins, but figured I should start mining during the nights at my university. I have 40 computers with NVIDIA Quadro FX 4800 at my hands. Is that a good graphic card to mine with?
Which software would you recommend me to use? All the computers have Windows 7 on them, and I have no admin access, so I can't install anything on them. It would be neat with some application that could be stored on a USB-stick.
I've tried bitcoinplus.com, but I have a feeling it isn't optimal.

Thanks in advance, and sorry if my questions are nooby.
