PC for games and family use

Rotor

Ok - I'm going to pull the trigger on this tomorrow morning http://www.dinopc.com/shop/pc/configurePrd.asp?idproduct=1636(gone for the gtx 660 gpu) but can someone just reassure me about the motherboard please.

Is the 'gigabyte 78LMT-usb3' ok or is the extra £17.60 cost of the '970A-DS3P' worth spending ?

Thanks

Edit : Oh well link just goes to 'standard' build - I have changed gpu to 'gtx 660', ram to '2x4gb' and power supply to 550w. Oh and gone for windows 7 not 8
