Hi all, very informative thread, many thanks for all the contributions.
My reason for posting:
I'm running the 5770 on 1.1 MacPro,10.7.5 for around 6 months, purchased from apple store. Easy install and I've not had any direct issues from this new card. Runs 2 x 23" LG HD Monitors.
The issue I've had which may or may not be related to the card is stuttery video streaming on various sites(youtube,facebook, vimeo etc) The streaming is done via Firefox latest release and I've had the issue on previous versions of Firefox since the install of the card.
Has anyone had this issue at all with their 5770?
If not, can anyone point me in the direction of a fix to this issue, I'm just ruling out the 5770 for now as it may be something else which is completly unknown to me at the moment.
Thanks all, hope your are well wherever you are 😁
Edit: I found this page on apple site - http://support.apple.com/kb/ht2848 I contradicts what apple shop said when I purchased this card, it seems it is now no longer the correct card!? Confused...
