everyone on the internet says wait for the Intel Core i5-3750K but I was looking at how good the hd 4000 graphics are going to be but it seems like its going to be a waste since I'm planning on buying a amd 6850 and they're not going to combine gpu power right? I was just reading about how ivy is mostly a graphics performance over sandy should I maybe pick an amd processor? I haven't been keeping up to date on pc hardware last time I built a computer was 6 years ago.
