Hi everyone,

 

Help desperately needed.

 

I've just installed a refurbished ATI Radeon HD 5770 1GB into my Mac Pro Early 2008 -2 x 2.8 Quad Core with 16GB of ram.

 

I was wondering if I needed to download certain drivers to allow this card to perform at its best?

 

Also, I have connected a HDMI cable from my mac to my tv (which I'm using at the moment for a monitor), but I'm unable to get sound. In the Output pane of Sound preferences, my tv/monitor is not showing up as an option.

 

Would anyone be able to advise me as to what I need to do to solve these issues?

 

Your help would be much appreciated.
