    Nothing new here - but I figure I'll add to the sample pool
    ________________________________________________

    Finally got around to throwing a new EVGA NVidea Geforce GTX 750ti (unflashed) in my Mac Pro (4,1 flashed to 5,1). Before I get into the nitty gritty, or if you are not interested in that at all, I'll make a couple of quick observations:

    1 The card replaced a Radeon 5870 the new card is a VANILLA GTX 750ti from NewEgg - $135 (model 02G-P4-3761-KR)
    2 The GTX 750ti to my simple (aka non-gaming) palate tests and "feels" just as fast as the 5870. I'm sure many will split hairs differently, but that I how it makes me feel, and my wife says that the important thing :)
    3 The Power consumption on my Mac is about 20 watts under a light load and about 105 watts less under a heavy load with the GTX 750ti
    4 Interestingly when the card seems to experience a light vs a heavy load (based on power consumption) is different between the two cards (additional RAM?, GPU efficiency?). For instance simple benchmarks like XBench and NovaBench made the Radeon jump significantly in power consumption (~+60W) but barely made the Nvidea twitch (~+15W)

    Benchmark 5870 GTX750ti

    Cinebench 11.5 36.57FPS 30.56FPS
    Novabench (graphics) 194 193
    XBench (3X video parts) 114.80 118.97

    Specifically in regards to the NVidea GTX 750ti? Or just in general? What kind of issue have you seen or heard about?

    I'm going to guess you haven't run it.

    Do some reading on this page

    MVC needs to read up on how to include links so as to not waste peoples time chasing down threads. ;)

    He meant read this page.

    Right now I'm showing as running:
    OS X 10.10.2 (14C109)

    Are you referring to Security Update 2015-002 1.0?

    And yet, even with the fish handed to him, no luck. Hence my suggesting the fishing pole.

    How'd you actually get it working? I have a fresh OS X 10.10.3 install, latest Nvidia drivers, power cable. But just get a black screen on boot (no beeping).

    I'm wondering too, as I'm thinking about getting such a card for a 4,1/2.66 and don't really know anything about what's out there now -- especially what can be simply tossed into the machine with little or no hassle. :)
