People who told you flat out no are right. If such cards can be modified to be shared on the multiple machines they wouldn't be so cheap. And lets say if you succeed in doing so how are you gonna get that graphic card to work on such PC's with 3 gb memory or even 2 gb memory. And not to be rude or anything but if you download that pdf file which list specs and info about it it requires a load of power and then to utilize that graphic card on machines you need a prettygood rig too so we are talking about more dollars here. Now all you are thinking is to put all that work on a little graphic card that can only run game like watch dogs so barely. Just think about it, people like nvidia and amd although think about themselves first but they also need to sell their products so if they made a card like 1000 dollars worth there is a reason.
