Due to the old one dying, I need to replace the graphics card in my Mac Pro 1,1. Anyone know a place where I can get a HD 5770 for a *reasonable* price. It's utterly ridiculous that Apple is still selling this thing for 23,800 yen here in Japan, when a new 5770 PC version goes for about 7,500 yen - less than a third of the price. I've heard they can be flashed, but I simply don't have any way to do it, since my only available machine is the Pro, and it's out of action at the moment. Alternatively, I've heard that unflashed (PC) 6XXX series cards will work out of the box with Lion excluding the 6890/6990. Is this correct? If so, is there any way I can get this to work, because my Pro is currently running Snow Leopard. I'm kinda confused about the best route to go down, or what is and isn't possible, so any advice would be appreciated.
