I want to hook a Mini DisplayPort 24" LED Cinema Display to my 2006 Mac Pro (it's actually the 2007 8-core refresh (specs), dual processor 3 GHz Clovertown quad core Xeon X5365 with 8 GB 667 MHz DDR2 FB-DIMM RAM, identifier MacPro2,1). This machine shipped with the ATI Radeon X1900 XT video card (with two dual link DVI ports). It has since been upgraded to the NVIDIA GeForce 8800 GT upgrade card for first gen Mac Pros that Apple offered after-market (here).
The Mini DisplayPort video cards that ship with the new March 2009 Nehalem Mac Pros are also being sold by Apple after-market. They're saying the NVIDIA GeForce GT 120 (here) is compatible only with the new 2009 Mac Pros, but the ATI Radeon HD 4870 (here) is compatible with both the new model (2009 Mac Pro) and the previous model (2008 Mac Pro).
So there are two video cards available for the Mac Pro, but allegedly neither of them is compatible with my 2006 Mac Pro. Google turned up this thread (" Radeon 4870 in 2006 Mac Pro? " on hardforum.com) where they say the 2006 Mac Pro has 32 bit EFI, which makes it not work with the newer video cards. Also, the PCI Express slots in this machine are PCIe 1.1, whereas the 2008 Mac Pro's are PCIe 2.0, as are the slots in the new Nehalem 2009 Mac Pro. But wikipedia says
Alternatively, if the newer video cards won't work in this old Mac Pro, then what about an adapter? Apple sells Mini DisplayPort to DVI adapters (here and here) which allow to plug DVI displays into new Mini DisplayPort macs, but so far I can't find any DVI to DisplayPort adapters, neither from Apple nor from third parties. Do such adapters exist, or will they any time soon?
What do you guys think? Is there a way to get the Mini DisplayPort monitors hooked up to my rig? I don't think I can justify upgrading my cheese grater for another 2 years probably...

so maybe there's a chance that the new card will work in my old Mac Pro, even though Apple doesn't explicitly support it? I'm thinking of just buying one to try it, and returning it if it doesn't work. What do you guys think? Is there any chance it will work in my machine?new PCIe 2.0 graphics cards are compatible with PCIe 1.1 motherboards, meaning that they will run on them using the available bandwidth of PCI Express 1.1
