better replacement for ATI Radeon HD 5770

Hello. I have in my Mid 2010 Mac Pro the ATI Radeon HD 5770 1024 MB. What graphics card is out there that has better graphics and also supports 3 to 4 monitors easily? My budget is in the 300 to 400 range. I've seen the EVGA GeForce GTX 680 for Mac, which is amazing, but out of my budget. I need to get three monitors running soon.

Mac Pro, OS X Mountain Lion (10.8.2), FCPX 10.05, iPhone 4Gs

The 5770 support three monitors today, provided you use ACTIVE Single-Link DVI adapters [that have signal boosters in them] available for about US$35. That will work up to 1920 wide or 1080p.

Thanks for responding. I went through **** with those adapters, but I'll try again. I bought the kind that had DVI to HDMI. I wanted to run two mini dvi to my monitors and the one large DVI to an HDMI based HD screen via an adapter, but that configuration just didn't work. I'll check out those adapters and give it a try. Thanks

It's not the USB data that is needed to run three displays. It's the extra POWER. If you read the Apple article, they say the only solution they endorse is their US$100 Dual-Link adapters. Check the table at the end of the article.

Readers here have found that if you have two Brand-X Powered adapters, aka active adapters, it also works fine. These do not always require another USB. If designed recently, they can pick up a power pin in the Mini DisplayPort interface.

AMD (makers of the 5770 and 5870) lists the qualified POWERED adapters that meet their most stringent requirements. Look down the page and you will find several qualified Active Mini DisplyPort to various others, such as HDMI. These adapters are available from other outlets, such as Amazon, sometimes for far less than the Apple adapters.

The other desktop monitor will plug directly into the DVI port on the card and the 40 inch tv will still connect via HDMI over the second Mini Display port.

That will work only if you use an active Mini DisplayPort to HDMI adapter.

but you should confirm that they are really active before buying 500 of them.


You can connect a DVI to HDMI adapter or cable to an active Mini DisplayPort to DVI adapter but that won't give you any audio over HDMI. You could connect the DVI displays to the Mini DisplayPorts with active adapters and use a DVI to HDMI cable or adapter from the DVI port to the TV.


If you want audio via HDMI, you can use audio from the Mac Pro's optical output with this DVI to HDMI converter:
