I'm running a 2x 2.66 intel core duo 1,1 Mac Pro from 2007. My current video card is a Nvidia 7300 GT. I want to upgrade to a better card for gaming in windows xp boot camp and Adobe products. The available upgrades i've seen are: Nvidia GeForce 8800 GT 1st gen mac pro graphics upgrade kit for $250 ATI Radeon 4870 HD from apple for $350 ... or i can spend half as much for a better PC card that ill have to flash. This option sounds very enticing, but risky and i know next to nothing about flashing. From what i've read, flashing a PC ATI Radeon 4870 is one of the safest ones to go with. All i can really do is follow a guide and hope everything turns out alright. The most promising guides i came across are: http://web.me.com/jacobcroft/4870Flash/4870Flash.html http://boeglin.org/blog/ (scroll down to "How to flash a PC 4870 for a Mac Pro, using only Mac OS X") The second one in that list is more along the lines of something id feel comfortable doing myself, but i would need the exact same card the guy used. Can anyone provide a link to this exact card: Sapphire 4870 with 512MB VRAM (early model, based on ATI's reference design) Does anyone know of any other reliable 4870 flashing guides? I don't wanna buy the wrong card or destroy my computer. Thanks.
