A $200 nVidia board is a round-off error compared to the price paid for the software license and support. If you were only doing 2D stuff, I'd say it might be fine, but your complaint about glxgears tells me you want real-time 3D. So, get a real 3D board. Assuming by "Cadence" you mean one of the Allegro PCB design products, Cadence has a document that makes this requirement explicit: http://goo.gl/V2E9S Quoting from page 15: "A dedicated graphics card with hardware OpenGL support and a minimum of 128MB dedicated (not shared) video RAM and a 128-bit bus interface. (256MB or more is recommended.) We also recommend that the card be workstation certified. (We do not recommend motherboard-based graphics solutions.)" Congratulations. Now you don't have to upgrade the OS. :)
