H67
Each Socket 1155 CPU all have in built graphics, and to be able to utilise that embedded graphics card the motherboard must have a video output such as a VGA, DVI or HDMI port. All H67 motherboard have at least one video output so that the CPU GPU can be used. Whilst this is a great feature it is worth noting the integrated graphics are not much cop and only really suited to HD video playback and very basic gaming. The main advantage of this is to eliminate the need for a small sub £30 graphics card and to bring down the overall cost of a workstation PC or media Centre that does not require a dedicated graphics card. The H67 like all the other chipsets does support dedicated graphics cards too, so should the need to add a higher end graphics card arise, it is a straight forward procedure.
The downside of a H67 chipset is it supports very limited overclocking even if an unlocked ‘K’ Series CPU (i5 2500K & i7 2600K) is installed. To the overclockers, this is a completely no go chipset, but for everyone building a sandy bridge system on a budget it makes a great choice.
H61
Another chipset that was released late on. The H61 is pretty much the same as the H67 but are designed for the bottom end of Sandy bridge builds. Whilst marginally cheaper than H67 chipsets they lack the following features;
Native USB 3.0 ports
Native SATA III ports
Clear Video Technology
RAID
They also have less memory slots (only 2), Less PCI-E Lanes and less USB 2.0 ports.
H61 is only recommended for users that can do without those features, are not too bothered about the upgrade potential of the motherboard and simply cannot afford to step up to a H67 chipset.
