Okay, a weird question here, I have a 2011 27" i5 3.1GHZ, 6970m 1GB, 12GB RAM, 1TB iMac. Now, obviously the iMac has the AMD 6970m as its GPU, but does the sandy bride i5-2400 3.1GHZ come with Intel HD Graphics? Ive tried to do lots of research but I didn't find much, so I was hoping somebody here knows if this is true and if I can combine the power of both GPU's if thats possible. Thanks for any info in advance
