I use the R9 270 so I don't know what the built in graphics can handle but youtube, google and fellow users sure do! And no if you want the overclocking pentium you gotta go G3258 and get a z87/97 board to overclock it, more monies out of your pocket. In that respect I think the AMD build will be better suited for you, especially if you don't want to put anymore undo money into this machine in the future.
