I would really like to buy the software and all the hardware system, but first i've got 3 questions: Would DIYeGPU-Setup-110b5 work on my MacBook4,1? is there any problem if I connect my eGPU to the mPCIe instead of a thunderbolt? (I know i'll get only 1.x connection, but still better than intel 965 chipset) I have Win7 and Boot Camp 3.1 Patch, would a clean UEFI installation give me certainty to have less problems? Which ATI/Nvidia should i buy, if i'm searching for best compatibility and good quality/price? (play batman arkham city is my aim...)
