I am currently using a stock 6600 GT and flashed 7800 GTX512 that will be connected to a 30" 2560x1600 Apple Cinema Display. The PowerMac has dual 970MPs at 2.5GHz (two 970MPs are about as fast as a single AMD FX-8300), will possibly have 20GB of DDR2 (currently have 16GB, but am going to order some more RAM today and see if it works), has two HDDs, a 500GB and a 2TB, and 32 total PCIe 1.0 lanes. The junk GPUs are holding the entire system back, but there is no way to upgrade them. When a GPU that is not flashed to a firmware compatible with the PowerMac is installed, the screen just stays black and the card doesn't initialize, even with OSes like Debian, which have drivers for modern cards.
Questions:
1.Why do cards to have modded firmwares in order to function?
2. Is 750 Ti is the fastest nVidia card that has one or no 6-pin PCIe power connector?
3. How hard would it be for someone who has no experience in any sort of programming other than markup to create a proper ROM for a card such as a GTX 750 Ti or R9 270?
4. How much would a programmer charge to create a ROM (I'm not looking to hire here; I'm just looking to find how much it would cost)?
3.
....A. If a 750 Ti had a firmware written, would it work in OS X 10.5.8, or would it only be usable in Debian due to lack of drivers?
....B. If a 750 Ti would not work, what is the fastest card that can be used in OS X 10.5.8?
