Closed Early 2008 xeon quad core mac 3.1 graphics card

[Sardine]

as Title looking for a Pcie-e graphics card for my lads Mac Pro 3.1

its the A1186 quad core Xeon

has a (I suspect dead) Ati 2600 XT,

chimes, boots to os, can eject the cd tray etc, no video (common issue i believe with the 2600 xt)

I do have a 6870 and I believe this will work (when the mini 6 pins cables arrive) without flashing, just a black screen until the OS boots.

but would prefer a mac card if possible

the one that are compatible I have read are

Graphics cards for Mac Pro (Early 2008 )


ATI Radeon HD 2600 XT
NVIDIA GeForce 8800 GT (part number 630-9191 or 630-9897)
NVIDIA Quadro FX 5600
ATI Radeon HD 4870, offered as an upgrade kit
Note: The Radeon HD 4870 card requires Mac OS X v10.5.7 or later.

any help would be great

thanks
