So I recently acquired a GTX Titan X for my Mac Pro and I have had 0 issues so far... nice card and the CUDA acceleration seems really nice and fast for Adobe Premiere Pro editing/rendering 4K video. I'm using it the same way as my GTX 980... web drivers only. Never thought about flashing it. I started looking into flashing, but it seems that the only benefit at this point is enabling a boot screen? Am I correct in this? I noticed MacVidCard's site mention that it will fun at PCIe 2.0 speeds, but I believe the card already runs at 2.0 speed with the latest webdrivers. Can anyone else with the experience with this elaborate? Thanks!
