My i7-3770K is just ordrered, I have no it on hand now and unable to try myself yet.
The questions are
1) Do I need to connect monitor to internal graphics port to use OpenCL on GPU part of Sandy Bridge? Or drivers will load either I've no monitor connected to it. OS is Windows7 x64
2) I have motherboard with P67 chipset. So, I've no internal GPU-related settings in BIOS (enable/disable, GPU frequencies).
Will OpenCL work on HD4000 on this M/B? Do I need to change it to something with GPU features enabled (Z77 chipset or so) ?
