Hi friends,
I am interested in buying a new core i5 processor and I need to know what is the best USB 3.0 supported motherboard.I want a board that can easily be overclocked
On lower-end LGA 1155, assuming this is an LGA 1155 question and Sandy Bridge CPU, the Gigabyte UD3 lines are good. If you're not going to game then look at the MOBO's with HDMI listed in the bottom column; the Intel HD Graphics 3000 is perfectly fine for anything 2D including watching BR movies.
edit: I would recommend if using onboard graphics that you stay with Sandy Bridge with 850MHz Graphics Clock rate ; See -> http://en.wikipedia.org/wiki/Sandy_Bridge#Desktop_processors Also see the Intel specs -> http://software.intel.com/en-us/articles/quick-reference-guide-to-intel-processor-graphics/
