Yes. It's happened before.Before these went up people seemed certain they would work on the 2008 Mac Pros. Could this still be the case, despite the Apple Store saying only for 2009 and 2010 models?
'08 and newer MP's do use EFI64 firmware.Does anyone know how Apple could prevent the card from being run on a '08? Aren't they all EFI64?
Good point - I'll keep a look out. I guess a number 2009 owners will be upgrading. I'd rather get the 5870, but if they prove to be incompatible then a used 4870 seems like a good idea. I currently have the 8800GT which is fine though I gather that many of them failed. Have many of the 4870's failed?I will be selling mine when the 5870 is available and I bet a lot of others will be too.
Keep a close eye on BarefeatsYes. It's happened before.
They claimed the GT120 only worked in the 2009 systems IIRC, when they did work in the 2008 (it uses EFI64), and the HD4870 was claimed it was incompatible with 2006/7 systems, when it worked in those as well (uses EBC).
We don't know for sure yet on the PCIe version of the 5770/5870, as it's not been tested. Someone will play guinea pig... err... test it out I expect.
