Despite reading the numerous threads on this forum, I am still very confused about Radeon HD graphics card support for my Mac Pro (MacPro5,1) beyond Radeon HD 5770 and 5870.
From what I read, Radeon HD 7950 Mac Edition is the last "native" card supported in the Mac Pro that can boot to both Mac OS X and Windows without the need to flash the ROM in the card.
Beyond this, among ONLY reference cards currently being sold on market by AMD (no secondary manufacturers, including Sapphire), what is the HIGHEST Radeon graphics card that I can install in my Mac Pro WITHOUT the need to flash its ROM? I need to see the boot screen, as this is important for me because I frequently switch between booting to Windows and booting to OS X installed on different hard drives). For example, I am seeing a lot of high-end Radeon HD cards being sold on eBay claiming to be Mac compatible, but the ads for these cards are suspiciously low on details, particularly on whether or not these cards are pre-flashed or not.
Note that I am not interested in any "flash-requiring" card.
Please help... Thank you kindly.
