Help with evga GeForce gtx680 4 bg pc version on a Mac Pro

[blackeycole]

I just received the following Mac Pro tower it is a 5.1 dual 6 core with 64 gb ram and 8 to hdd space but the gpu is lacking connections. I wish to use mt three 23" displays plus my Wacom cintig and the current gpu only has one dvi port and one mini display port.  Which I used a mini display to hdmi to connect to my Sony PS3 monitor till I move back home.  I have a pc gtx680 4 gb gpu from my pc days.  I'd like to trade for a mac native 4gb gtx680 or have it adapted to the mac so that updates will not cause a problem.  I've read where this has been done but I no longer have access to a pc to flash the gpu I have a pc laptop and the Mac Pro plus this iPad I'm on now.

so will it work as is or does it need flashing?  I know I'll need the two power cables I have two coming.  Plus I think I have a couple of 6 pin to 6 pin cables around in my storage bag.  I can download the mac drivers if needed.  I'm new to the mac desktop world besides a iPad and iPhone I had a Mac mini until it died.

what are my options?

Hi there, this should work without flashing with El Capitan onwards. You will need the power connectors, but you will not see the apple boot screen as you boot. It should work fine but will stay black till you reach the desktop.
