Do you have an LGA1156 board and wonder why your onboard video isn't working? It's probably because there is no GPU integrated on the board itself, it is supposed to be on the CPU and new CPU's from Intel don't come with it!
I was shocked to learn that you can buy a motherboard with onboard video which doesn't work. I never knew it was being done or possible, but to make it worse the latest Core i5's don't have video on the die of the CPU.
This means having on-board video is useless and meaningless. It took my surprise and caught me off guard and there's a lot of other builders/techs that don't know or will find out the hard/annoying way like I did.
To make it more confusing, I believe CPU's before my Core i5 750 DO have the video on the CPU die (Core I3's and Clarkdale I5's), so some may still be caught off guard. This is a really silly move by Intel which makes no sense at all.
I think I'll stick to AMD and go with a 6-core option.
