Best SMBIOS for HD4600 and HD6770 (Flashed as 5770)

[nightlite]

Hi, I have the following configuration

Software - 10.10.2 - Clover
Motherboard - Z87X-UD3H
Graphics (Initial in BIOS) - PCI slot HD 6770 (Reflashed as 5770 so I dont have to inject ATI) - two 1600 X 900 monitors
Graphics - HD 4600 - one monitor 1920 X 1080

Currently running Mac Pro 3,1. Noticed graphics performance is slower in system. Is HD 4600 being treated as the main graphics card because I sure would like to take advantage of all the power HD 6770 offers.

Yeah, I was hoping someone can help me with that. 5770 + HD 4600 = ?

By my estimations, mac pro 3,1 is the best but it doens't explain the lacking graphics performance - like all the power of the 5770 isnt being used...

Are you using the IG for monitor connection?? If not then disable it.

But i don't think there is an Apple product with your processor and AMD/ATI discrete graphics (Not sure).

Better you check the details of the definitions iMac14,1/ iMac14,2 / iMac14,3 and choose one.
