[SOLVED] Replacement/Upgrade of RADEON HD5770, 1 GB

[oeksen37]

I am owner of an "old" Mac Pro, Model MD 770, bought in Nov. 2013 and equipped with an ATI HD 5770, 1 GB Graphics Card. 2 days ago my "Eizo" Color Edge CG 276 Screen, probably bought 3-4 years ago, wouldn't any longer receive a video signal and went into BLACK. It's my own assumption, after having undertaken my own tests, that in fact it IS a display failure....

Well, my question: Which NEW card should I settle for. I am NOT a gamer, however, being a photographer, the new card should be able to provide a reasonable solution. Which card/brand name, specs, would be the right successor to the above, and WHERE may I be able to buy it from?

Grateful for any prof advice...

If the display failed, why are you replacing the card instead?

I agree with popatim, why replace the graphics card when it's the screen that's dead?

To answer the actual question, the best graphics card you can put into these aluminium chassis mac pros (mine's a mac pro 4,1 from 2009, single xeon W3540) is an HD7950, before running into driver issues. You might be able to get away with an HD7970/R9 280, but I haven't tried that. I currently have a reference HD7950 in my mac pro, so that's all I can verify works with Mac OS 10.6 through 10.10. My machine is too old, it won't let me update to any OS newer than 10.10.
