I'm speccing up a budget gaming box for my nephew. The G31 chipset motherboards are by far the cheapest. I have been to the Intel website and done a chipset comparison: http://compare.intel.com/pcc/showchart.aspx?mmID=34470,36521,29001,30686&familyID=10&culture=en-US So far as I can tell the limitations are 4GB memory max, as well as a few less USB and SATA ports. Is there anything else missing? Is there less overclocking headroom? I am looking at Asus boards. Onboard video will be disabled, and there will be a PCI-E x16 video card and budget C2D processor to go with it.
