Is it possible to completely disable the integrated graphics card without it hurting the performance? Have you had any issues with it?

Yes,you can disable the onboard GPU and no,it won't hurt the performance at all. In the BIOS,go to Advanced>System agent configuration and change the "Initiate graphic adapter" to "PCI-E/PCI" (Setting it to iGPU will use the onboard GPU)
Is it possible to have both gpu and and PCI-E enabled? im looking into using both the onboard video and my gtx 580 mis 3gb
