I have an Acer V3-571G with core i5 3210M and GT630M Graphics card.
Ethernet works well and HD 4000 works with 1366x768 resolution and 512MB VRAM (I don't sure that this card works perfectly because I didn't test Qe/Ci but I think it did because finder bar is partly transparent)
Some trouble I didn't solve is Wifi doesn't work (AR9462), I can only find 2 kexts for this wifi card, but none of them are loaded
The second is CPU temperature, it always above 55*C - 80 *C, even speedstep works with 8 states (macpro 3,1 sysdef)
I heard that Ivy Bridge CPU has Native power managerment in ML 10.8.2 12C60 (kext X86platformplugin loads instead of AppleSMC... kext) that better than AppleSMC..., but I untill now I can't manage to install ML 10.8.2 12C60 because some issue with installer, "still waiting for root device" error messed me
Hope someone will help us to enjoy full hackintosh
sorry for my bad English, I'm from Vietnam
