Does the MID 2011 27 inch Imac have BOTH the AMD RADEON 6970M & INTEL HD 2000 graphics cards???

i have the 3.4 ghz (up to 3.8 with hyper-threading) mid 2011 27 inch imac. It has 16 gigs of ram and an amd radeon 6970M with 2 gigs of vram. I actually just had the card replaced by apple thursday bc it was displaying vertical lines and black screens. They replaced it free with apple's graphics card replacement program. Thank God bc its out of applecare. I was looking for better temperature monitoring apps bc i only use lubbos fan control while in bootcamp. Works great to adjust the fan speeds and keep my imac running cooler but always displays crazy incorrect temperatures for everything and also only in Celsius. So i just searched and download/installed several temp monitor apps. 9 out 10 sucked and either didn't recognize the gpu i have or only had Celsius modes. I finally tried the amd monitor app from amd 's website and another i cant remember the name of it since i tried so many. Both the amd monitor app and the last one i tried showed BOTH the amd radeon 6970m as well as the intel hd 2000 integrated graphics on board. I was puzzled because i knew the integrated cards existed in macs but usually only the macbook pros or macbook airs.,not the imacs models. I have heard time and time again that disabling the integrated card in the bios results in much better performance with gaming bc it only uses your primary better gpu card and not both or just the integrated one. But i want to be sure before i mess with the bios. I will definitely at least load the bios to see what it says and if it only shows the amd radeon 6970m then i know its not true. But if shows both i will definitely try \to disable the integrated one to see if i get better performance while gaming in windows 8.1 in bootcamp. I usually can play all the latest and past games in hgh to ultra settings on 2650 x 1440 with my radeon card. Works perfectly,u just have to keep the fans high and limit your playtime to avoid overheating or damaging the imac or gpu. If you are more familiar running ,monitoring apps and can actually understand what all the info means, can u please tell me what yours says. Assuming you have the same 27 inch model i have or close to it.

That's what i've always thought. But still i will definitely see what he bios or CSM-bios tells me about the gpus. There's a lot of things apple hides form the everyday user. Example: did you know there is a hidden partition next to the recovery partition that contains data for the apple internet hardware test?? Neither did i until i went to the apple store and they were apple to diagnose my gpu problems when all i would get was a black screen. they simply booted from this hidden partition by accessing the internet hardware test and boom my screen worked again, at least for the test. This whole situation reminds me of how in my older 21 inch imac dual core duo i was under the impression that i had an amd radeon hd 2600 pro, yet when under windows i could see it as an amd radeon XT. 2 different cards. I had to manually install the drivers for the hd 2600 pro to get the performance i wanted in bootcamp for gaming at that time. After i installed the correct drivers, the card read properly in device manager as the hd 26000 pro and not the XT ****** version. I just cant shake that the amd monitor utility and the other temp monitoring app i tried both showed 2 cards, the amd radeon 6970m and the intel hd 2000. Theres another instance where i saw the video ram displayed as 8 gigabytes when i should only have 2048 mb or 2 gigs. How can that be i said?? Now it makes sense if there is also an integrated card. Its combing the total vram from bOTh cards and system shared memory to display that total vram of 8 gigs.Anyays thnak you very much for your comments and your help. I will report back what the bios or csm bios tells me.

So yo are saying It DOES or DOESNT have 2 cards?????? By that i mean my MID 2011 27 inch Imac
