How To Flash Your Video Card For Mac Pro

Hello, i acquired a 2008 3,1 mac pro late last year, and i decided that i wanted to do i few upgrades to it to make it 'work flow friendly'. So, ive done processor upgrade (from 4 to 8), now i aim to do a graphics card upgrade, only thing is theres alot of loose info floating around on what does, and doesn't work.

If not repackage it and send it back. Amazon is usually good with returns even after you have opened it. Macvidcards recommends nothing above a gtx960/770/680 or AMD equivalent in those machines. There was a huge increase in cpu power when the 4,1 came out so they can handle a faster gpu. The Harpertown processors in the 3,1 will hamstring anything faster than the cards mentioned above.

Mac os alarm clock. You can still use faster cards if that's what you have but you won't get maximum performance from them. Im going to select your reply as the answer, just so i can let this thread die. I havent touched that machine in over a year, and have moved way pasted what i was doing with it.
