Hey guys, I definitely need your advice. I have a Mac Pro 1.1 that has been upgraded pretty well, 32 gigs ram, 240 gig SSD (just installed OSX El Capitan thanks to your forum), and an ATI 5770. The 5770 is the sticking point, Bethesda says minimum requirements are NVIDIA GTX 550 Ti 2GB/AMD Radeon HD 7870 2GB or equivalent. Now, I am not afraid of modding things, but it's not really a hobby for me anymore so I am definitely out of the loop. I need the boot screen, as I boot into windows for gaming/CAD work, and OSX for everything else. Using google, much of the information on upgraded cards is from 2012 or 2013, so I'm sure there are more options now at the end of 2015. What's my best bang for the buck to meet minimum requirements?
