Hello everyone! i browsed around and didnt find the answers i was looking for and didnt want to revive a dead thread. I am planning on purchasing a Mac pro 4,1 (2009) with dual quad cores. It is coming stock with a ATi RADEON HD4870 512Mb....that simply doesnt cut it for me. i have a GTX680 2GB laying around and read i can flash the rom to make it a Mac-able card.... The GTX680 has a 8 pin +6 pin...How can i power the 8 +6 or do i only need to power it with 2 6pins? Any suggestions would be nice, i would of gotten a newer Mac...but my budget doesnt allow for it.
