    hello
    i upgrade my mac pro 1.1 with a xfx hd 5770 PC card,that works very good after os x has booted
    im running lion with latest updates. and i cant open any 3d app or opengl,its crashes
    i installed steam and tried to launch half life 2,it show down its opening but the icon goes away after 2 seconds. also i tried other games but same result its icon show for a couple of seconds then it goes away.
    in windows games play perfect.
    i downloaded gputest,but when i hit run benchmark i get "gputest quit unexpectedly"
    using firefox on youtube with latest flash player installed, video works perfect
    what could cause this problem ?

    There is always a reason.
    In this case your GPU.

    Check whether this GPU is supported in Snow Leopard.

    Pretty sure this card will profit from an EFI flash (especially in older OS X versions), have a look over at netkas.org.
    Some cards where buggy in Lion when used without injection, I guess yours is one of them.
