Need help with my 580gtx (vesa and a doubt)

[skylarr]

Hello, i have a Asus Rampage iii Extreme and a i7 920 and Lion 10.7.3

 

Anyway i was quite shocked to see that my Asus 580 gtx doesn't have a vesa mode that goes up to even 1920 1080 let alone further than that, is there any way to flash another bios with that vesa mode or to edit the bios to add it? booting up looks messed up due to that .

 

Also i installed lion , added dsdt etc but my 580gtx will only work at full screen when i use the 5xx enabler, is it normal for the 580 to not be at full resolution after fresh install and having to add vendor id?

 

Also is it beneficial or even possible to add graphics cards to the dsdt or it's not worth it performance / easy of use wise?

 

I also edited AppleGraphicsPowerManagement.kext and added the thresholds under macpro5,1 , anything else i need to do squeeze the most performance from this card under lion?

 

Thank you very much
