Thorough Pro Graphiccard comparison (Quadros and FirePros)

Here they compare the current and previous Quadros and FirePros.
Note the programs they test with are mainly for visualisation and not pure CAD, but it does show the cards strengths.


Too bad no mobile cards on here.

I expect the mobile versions of the chips to be around 20% slower than the workstation versions as they usually are downclocked to not run as hot. But you can use the charts and then can google each chip for comparison with the mobile version. The conversion should give you the info you need.
