i got mac pro 1.1 upgraded to 2.1 from my friend and it works well,i upgraded video card,installed 10.9.5,but video card working 50% power and gnu fan is so noisy as hell,games running 10 fps and benchmarks showed me 15-29 fps,can someone teach me how to fix this ? i downloaded drivers from cindori,but it was for 1gb version,now my video card is radeon hd 6XXX series 1024 mb and work more quietly !

Cindori doesn't have drivers, he may have some roms, but the 6870 EFI was developed by Netkas and is 64bit only


So it won't ever help on 1,1

May as well flash it back

Probably time to do rsearch instead of blindly flashing things
