    I have a 2009 MP flashed to 5,1 running a Zotac GTX 750ti with the web drivers. Recently I found locally a Mac edition GeForce GTX 680. Its at a reasonable price but I am unsure if it's worth the upgrade. I still have the GT 120 in my Mac so if need be for a boot screen I can use that card. Do I keep the 750 or change for the 680.

    I had a 4Gb GTX680 in my old MP and it was bloomin awesome.

    I think you will find that the 680 will smoke the 750 for gaming

    Go for the mac edition; you will have boot screens.

    Do you generally need GPU power? If yes, why not? If no, why upgrade?

    you can just grab a normal PC 680 if you want and DIY flash it
    or a 670 and not flash it. (you dont need to flash a 680 a normal pc one is fine)

    but only if you need more speed, then you also have to look at the new rx460 if your on 10.12

    Also you can DIY flash for Radeon 7970, which mostly equal to GTX680 performance

    I would grab the 680, then you can pull out the 120 and 750. You will have a better GPU and gain an open PCIe slot that can be used to add a blade SSD, usb 3.1 or anything else you might need.

    BTW, I have a flashed EVGA GTX680 in my 5,1. Love it!

    Well I already have a usb 3.0 and usb 3.1 card in the system. I am leaning towards taking it and like I said the price is pretty good. Got the 750 because it is low powered so I think I will need cables if I do take it.

    You will need two mini 6 pin to 6 Pin cables. I grabbed mine on eBay

    You won't regret the upgrade.

    Cheapest cables work as well as the most expensive ones. Pretty sure there's only 1 manufacturer for the Mini Fit Jr. connector on the motherboard, and even 20 AWG wire won't have much voltage drop since it's a fairly short length.

    Well I think I will pick it up tomorrow. It does free up a pcie slot and has boot screens. May try and resell the Zotac card. I am assuming since it's a mac version it will be good until I can no longer get os updates own this machine.

    GTX 680 is a great option it will work without the web drivers so no need to wait to upgrade OS versions
