Hi all! First of all, I have just found out the 'netkas' way to change my MacPro graphic card. I have a nvidia 8800gt which came with my Mac 2 years ago and well... I use it for many things like postproduction, video editing, 3d and gaming (gaming nowadays more than never with steam and before with world of warcraft bla bla bla...) The thing is that when I use the card for 3D or gaming it sounds like a taking off airplane. From 0 to 30 seconds the card increases the fan speed/sound. I clean my macpro about 3 or 4 times a year, even my card but, honestly, I have never open the black cover the nvidia has for avoiding a disaster... Ok I just want to know the best (or at least a better) graphic card. If it is a PC card, how could I make it work in my Macpro... I tell this because mac edition options are obsoletes I think... Thanks!!
