ATI Radeon HD 5770 Mac vs PC card

[PlainviewX]

How can I physically tell the difference? I bought one years ago, but I cannot remember if it is PC flashed or Mac.

I think that the Mac card is the only one 5770 that has DVI and two mDP ports.

think thats a photo of it, it has the plastic support that slots in next to the fan (think the pc ones just end without the anti sag support)
+ the ports as mentioned by owbp

Thank you. I have the PC version then as it has two DVI ports and only the tooth on the left side, not the whole square support.

I think that the Mac card is the only one 5770 that has DVI and two mDP ports.

Is there any noticeable difference in quality of output between DVI and mDP? I'm running a Dell U2412M at 1920 x 1200 on DVI and it looks pretty good. Wondering if it's worth buying a mDP --> DP adapter (on a Radeon 5870 with same ports).

 

[now i see it]

The quality will be identical. The signal is digital. With an analog output (vga) you can see a degraded difference.
