Ok someone might be able to help me, I have a mac pro 2009 with a NV GT120 GFX card. Ive been waiting to upgrade to a 5870 for ages and was hopeing Apple might release the update that has been on the website for ages anytime soon, but ive given up waiting now i have ordered the 5770 for now. anyways, will i need to install anything after i fit the new Ati 5770? like drivers ect, and can anyone point me in the direction of where to download these mac drivers please. Iam looking forward to the card arriving as i have also purchased a new screen, my trusted 24' Hyundai has started having trouble switching on and off so before it goes completely i decided to get another 24" which is big enough for me. I went for the HP LP2475w S-ips panel so iam hopeing these 2 will give me a good combination of GFX and visuals.
