Ok, I am going to review the Gigabyte board. My psu has a 4 pin connector at the end and a 8 pin connector in the middle of the lead that goes to power the cpu. Is this the only lead that can be used yo power the cpu? Also, i am using Win 7 ultimate. I only play wow. Would it be a good idea to upgrade to Win 10 and would i be able to use my 32 gbs of ram?
