I am in the process of building a new water cooled PC and I would like to test the new 780 Ti before stripping off the stock cooler and fitting the water block. I have the PC PSU which I can jump to power the card and I wanted to check the most convenient way of using my 5,1 to test the card. Here are what I was planning to do... 1. Set my boot drive to the Win7-64 SSD 2. Boot to Win7-64 3. Use a driver cleaner to strip the AMD drivers 4. Shut down and remove the current 7950 5. Fit the 780 Ti 6. Connect the 6+8-pin leads from the PC PSU and jump it to power the card 7. Boot the Mac Pro into the Win7-64 drive 8. Install the current nVidia drivers 9. Heaven/Valley test the card 10. Strip the nVidia drivers 11. Shut down and revert the 5,1 to its current configuration. Does that sound like everything I would need to do? Could I test on the Mac side in the same way without messing up my current Mavericks install? I do have a clone drive I can use as a temporary Mavericks boot drive.
