    In a way I want to say "**** apple", I am sure you know why and understand my feelings.

    Oh I own a "old" Mac Pro, btw.

    Mkey, what I want to do is replace my 7300GT with a 8800 Nvidia PC card. I know this will work only in Windows, and that I need to replace the 7300 to boot OSX.

    I'm ok with this. Why? Well because many other, Games, graphics and such is more important to me then the operative system. I will not completely move to Windows, but this is a great compromise for those who want a screaming gaming computer and one of the best Mac's available.

    Too bad Apple don't realise these needs.

    Anyway, I am thinking of a card like this

    These are my questions

    Will they work in my Mac Pro under Windows?

    What do I need to make it work?

    Will it fit? rofl

    and what are the differences between the cards?

    Sry for swedish site, just read the specs : )

    Well you've got one thing right.... definitely not going to work in OS X... as there are not GTX or GTS ROMs that'll work in OS X. Why not buy a GT though? Am I missing something, or is there some very special reason the GT doesn't work in OS X?

    The GT is cheaper and faster than the GTS, and the GTX isn't much faster and way more expensive.

    I guess my main thing is I don't know why the GT won't work in the new macs.. I haven't really looked into it. Do you know why?

    I heard someone mention something about EFI vs. BIOS, or something. If you need a system that supports EFI, and the older Mac Pros don't, then I guess flashing a PC GT to a Mac GT won't work, since... there wouldn't be one.

    But I see no reason why they wouldn't work in Windows, since uh, "Mac" Pros aren't Macs.. they're PCs.

    So I can't think of a reason it wouldn't work... you might want to try just popping in any spare PCI-E card, if you have one in another PC, to see if it works in windows. Personally the only graphics cards I have in my house are either ISA, PCI or AGP, so I'd be out of luck.. lol.
