Depends what your trying to do with it. The 750s are entry level graphics cards, and not meant for current games (2013 forward, like BF4, Watchdogs, COD:AW etc.). If your playing older games (2012 and older) it will be okay. While the new A10 is alot more improved over previous APU, this will be the BIGGEST bottleneck, and isn't made for gaming. APUs are to provide low end, low cost, low demand, low power solutions for the 90% other users out there (FBs, Youtube, etc.) not gaming.
If your into gaming, and especially modern games, you have two choices, either spend ALOT of money on the PC for a rig capable for these 2014 forward games (the ones you seen at E3) at around $1000US (AMD FX-8xxx, i5/i7-4xxx with a AMD R9 or Nvidia 760/770)...
