Hey everyone ... I did my reSearch on MacRumors and even if I didn't find exactly what I need, it seems to me that You guys have good knowledge about DaVinci resolve and CUDA and simmilar topic ... so this is my situation I have MacPro 1,1 with GeForce7300GT graphic adapter and SL 10.6.8 installed ... I need to have another gaphic adapter in MacPro that supports CUDA technology for DaVinci Resolve to run properly. Is it possible to pick PC nVidia card from osx86wiki SL 10.6.8 compatible hardware list that works OOB with just minor adjustments and to make it work along with existing GF7300GT in MacPro 1,1 on existing SL 10.6.8 that works perfectly (for now ) or that is possible only on hackintosh? My choice would be ASUS GeForce GT210 or GT240 because it only needs GraphicEnabler=Yes (as it is written in osx86). I do not need to use its GPU to do some heavy CUDA in DaVinci Resolve Lite ... only for practise. Monitor would be connected via GF7300GT wich would be used as GUI card. Also GT240 would be positioned in slot 1 and 7300GT would be positioned in slot 4. Does anybody have some experience with this type of dual graphic card combining and is this possible on MacPro1,1 or it is possible only on Hackintosh?
