I know there are threads in regards to this but would just like to know the current state of things before making the leap on a graphics card. A little confused by the current threads. Considering it seems to be the text Mac Pro will favor AMD I expect drivers for AMD cards to improve across the board. Just confused on a couple things so would love it if someone could clarify a couple things for me. in 10.8.3 & Beyond (Mavericks as well) is the 7970 specifically one like the MSI R7970 BE supported? (Other than boot screen), also is there anyway to flash one of these and gain a boot screen without losing the increased clock rates? Also what is the current state of the Titan and 780 on 10.8.3 and beyond (including with Nvidia Web Drivers) as well as with Mavericks I saw it mentioned previously that the 7970 only works at PCIE 1.0 Specs unless flashed, is this still the case or do we still need a flash to get it to PCIE 2.0? I think I will go with a 7970 over a GTX 780 or 680 because it seems that Apple is favoring OpenCL which AMD seems to handily beat Nvidia at this point. I do Video Editing and 3D Modeling, Animation, and Rendering. If anyone has any suggestions they would be greatly appreciated. Final Cut Pro X, After Effects, Lightwave, Maya (Student) Also this may sound dumb but could I later add an Nvidia card just for CUDA if I find the need in the future and run my displays through the 7970 and let the Nvidia do CUDA? (Probably a 780) and before anyone jumps all over me on this I am aware I will need a auxiliary power supply and will be doing that with this. Thanks in advance everyone !
